Description

TECHNICAL FIELD

The present invention relates generally to surgical instruments and more particularly to multi-function surgical instruments, hemostats, forceps, mouth gags, palate retractors, and sets of surgical instruments and expandable sets of surgical instruments.

BACKGROUND OF THE INVENTION

Surgical instruments are typically provided in a sterile package. The sterile package may contain an individual surgical instrument or may contain a selected number of surgical instruments that are grouped together as surgical sets or trays for a surgery. The surgical instruments are typically made of surgical stainless steel. The surgical instruments are expensive. Often there are upwards of 30 surgical instruments combined and packaged by the sterile processing department in a surgical tray for each surgical procedure. A surgical assistant or nurse typically opens the package, lays out the surgical instruments and organizes them on a stand or table based on the type of surgery and/or the surgeon's preferences. Laying out and organizing the surgical instruments takes up valuable operating room (“OR”) time.

After use, the surgical instruments are collected, loaded on a cart, sprayed down and covered in sterile drapes. Then the cart is rolled out of the OR and taken back to the sterile processing department. This process consumes valuable OR time. After removal from the OR, the surgical instruments are cleaned, inspected for blood and/or tissue and cracks, repaired (if possible), sterilized and repackaged for a future surgical procedure. Furthermore, the mouth gag needs to be disassembled, which involves removing screws, springs and the silicon guard. Repairing the surgical instruments is time consuming. Replacing the surgical instruments is expensive. Maintaining spare inventory to replace entire instruments and parts of the surgical instruments is expensive. Cleaning, inspecting, repairing, sterilizing, reassembling the mouth gag and replacing the silicone guard, and packaging the surgical instruments is labor intensive and is very costly. Furthermore, failure to remove all of the blood and/or tissue from the surgical instrument may also result in a hospital quired infections and/or contaminated surgical instrument or tray of surgical instruments.

In addition, the surgical instrument may fail during use, if for example, a small crack was missed during the inspection. Failure of a surgical instrument increases OR time while a new instrument is obtained and may result in injury to the patient. In addition, many of the prior art surgical instruments contain small parts, such as, for example, rivets, springs, screws, and the like. Occasionally, one or more of these small parts separates from the surgical instrument. When this happens during a surgical procedure, the small part may end up in the patient's throat or lungs. Not only does this provide a safety concern and increase OR time, but it may require an x-ray to locate the part so that it can be removed.

Accordingly, there exists a need for surgical instruments, and/or sets of surgical instruments that do not suffer from the deficiencies identified above.

DETAILED DESCRIPTION

The following includes definitions of exemplary terms used throughout the disclosure. Both singular and plural forms of all terms fall within each meaning. Except where noted otherwise, capitalized and non-capitalized forms of all terms fall within each meaning.

The terms readily disarticulated, readily separated, easily separated, separatable and the like mean that the surgical instrument may be easily disassembled and reassembled by the surgeon, a surgical nurse or physician's assistant during a surgery. Preferably, the surgical instrument may be disassembled and reassembled without the use of a tool. The term releasable connector does not include permanent connectors that cannot be easily connected and disconnected. Examples of permanent connectors are rivets, screws (that require a screwdriver to remove), bolts/nuts, and the like.

FIG. 1 is an exemplary embodiment of tray 102 of surgical instruments100. As discussed in more detail below, many of the surgical instruments 100 described herein are multi-functional and are configured to be used to perform multiple different tasks, each of which are conventionally performed by a single instrument. This exemplary tray 102 of surgical instruments 100 is configured for oral and/or pharyngeal surgeries, such as, for example, tonsil excision/removal. The exemplary surgical instruments 100 and concepts described and claimed herein are applicable to surgical instruments used in other types of surgeries.

The exemplary tray 102 of surgical instruments 100 includes a tray 102 and seven surgical instruments 100. The tray 102 may be a conventional tray that includes, for example, a bottom and sides. However, tray 102 may simply be a package for holding the surgical instruments. Tray 102 includes a multi-functional hemostat 110, a multi-functional modified Allis forceps 120, a ring blade holder 130, a plurality of different sized suction tongue blades 140, 140A and 140B, a palate retractor 150, a multi-function tri-view instrument 160 that includes a mirror, a tissue retractor and spatula retractor or elevator, and a curette 170.

While the tray 100 includes three different sized suction tongue blades 140, 140A, 140B, the tray 100 may contain fewer tongue blades. For example, an individual tray 102 may include suction tongue blade 140 for use with large individuals, e.g. adults. Another individual tray 102 may include suction tongue blade 140A for use with medium sized individuals. Similarly, another tray 102 may include suction tongue blade 140B for use with small sized individuals, e.g. children. While tray 102 is described with the selected set of surgical instruments, tray 102 may be configured with sets of different surgical instruments.

FIGS. 1A and 1B illustrate an exemplary pack 180 of surgical instruments 190. Exemplary pack 180 of surgical instruments includes a package 181. Package 181 may be made out of any material, such as, for example, cardboard, plastic, or the like. Preferably the package is made of a semi-rigid material. Preferably package 181 is made of a recyclable material. Package 181 includes a base 182, an optional cover 183, an optional back 184, and optional sides. Cover 183 may include a smooth surface that may include printed material, such as, for example, a company name, surgical pack 180 identifier, manufacture date, lot number, and the like. The surgical pack 180 identifier may identify the type of surgery the pack of surgical instruments 180 is configured for, such as, for example, Oral/Pharyngeal 3, which is configured for oral or pharyngeal surgery and include a size 3 suction tongue blade. Once pack 180 and the surgical instruments are sterilized, the pack 180 and surgical instruments are enclosed in a sealed package (not shown). Optional cover 183 and optional back side 184 may be excluded and the base 182 and surgical instruments, may be sealed in an outer packaging, such as, for example, plastic, that includes the surgical pack 180 identifier.

Base 182 is configured to retain the set of surgical instruments. The set of surgical instruments includes a multi-functional hemostat 110, a multi-functional Allis forceps 120, a ring blade holder 130, a suction tongue blade 140, a palate retractor 150, a multi-function tri-view surgical instrument 160 that includes a mirror, a tissue retractor and spatula retractor or elevator, and a curette 170. Pack 180 may contain other selected sets of surgical instruments depending on the type of surgery for which pack 180 is configured. In addition, the pack of surgical instruments may be custom ordered or customized for a particular surgeon, or surgery center's needs.

Base 182 is configured to hold the surgical instruments in positions that allow for the surgical instruments to be sterilized. Accordingly, a sterilization agent may flow around and/or contact all of the surgical instruments. In addition, base 182 is configured to hold the surgical instruments so that they may be removed in the order that they are needed in a surgery and so that they take up less storage space than conventional trays of surgical instruments.

Use of pack 180 reduces OR time. The surgical instruments are pre-selected for the type of surgery and are organized to be removed from pack 180 in the order that the surgical instruments are needed for that particular surgery. Thus, the typical preparation time that is required for an assistant to unwrap and organize a large set of surgical instruments, many of which are not required for the specific surgery is eliminated.

As discussed in more detail below, base 182 has a number of tabs and retaining members that are made from cut-outs/punch-outs in the base 182. The cut-outs/punch outs are bent upward and configured to retain the surgical instruments.

Base 182 includes retaining member 185A. Retaining member 185A includes interlocking flaps 185, 186. Interlocking flaps 185 and 186 are partially cut-out of base 182 and wrap around the multi-functional hemostat 110 and multi-function Allis 120 and interlock as shown. A pair of tabs 187 are partially cut-out of base 182 and are bent upward and outward. Tabs 187 are configured to fit through the ring handles of Allis forceps 120. Similar, a pair of tabs 188 are partially cut-out of base 182 and are bent upward and outward. Tabs 188 are configured to fit through the ring handles of hemostat 110. At least a portion of hemostat 110 is located on top of Allis forceps 120 and interlocking flaps 185, 186 wrap around hemostat 110 and Allis forceps 120 to retain them in place. Packaging space is saved by allowing earlier used surgical instruments to be placed on or above portions of later uses surgical instruments. In addition, such overlap places the “next up” surgical instrument in a ready position.

Base 182 includes a retention tab 190 that is partially cut-out of base 182. Retention tab 190 has an opening therethrough to receive a handle of the multi-function tri-view surgical instruments 160 to secure the surgical instrument in place. A second tab 191 is partially cut-out of base 182 and is bent upward to retain an upper portion of multi-function tri-view surgical instrument 160. Base 182 includes a retention tab 192. Retention tab 192 is partially cut-out of base 182 and bent upward. Retention tab 192 has an opening that is configured to receive and retain a portion of suction tongue blade 140. A second retention tab 193 is also partially cut-out of base 182 and is bent upward to retain a second portion of suction tongue blade 140. Another tab (not shown) bends upward and fits into the opening (not shown) in the suction tube 178 of the suction blade 140. Base 182 includes a tab 177 bends upward and fits into the channel (not shown) of ring blade holder 130. Base 182 also includes a pair of retention tabs 194, 195. Retention tabs 194, 195 are partially cut-out of base 182 and bent upward. Retention tabs 194, 195 have an opening that is configured to receive and retain a portion of ring blade holder 130. Base 182 includes another pair of retention tabs 196, 197. Retention tabs 196, 197 are partially cut-out of base 182 and bent upward. Retention tabs 196, 197 have an opening that is configured to receive and retain a portion of palate retractor 150. Another retention tab 198 is partially cut-out of base 182 and bent upward. Retention tab 198 has an opening therethrough that is configured to receive a handle of the curette 170. A final retention tab 199 is partially cut-out of base 182 and is bent upward and configured to retain an upper portion of curette 170. In this exemplary pack, retention tabs 191, 192, 194, 195, 196, 197 and 199 have an opening and a channel that extends to the end of the retention tab. The opening may be circular. The surgical instrument is pushed through the channel and seated in the opening. The channel is configured to be positioned over part of the surgical instrument to retain the surgical instrument in place.

This package configuration provides a presorted set of surgical instruments. The package is configured to allow an operator or surgeon to “open and operate.” The package configuration provides a ready to use set of surgical instruments that are preselected for a selected type of surgery. As described in more detail below, the surgical set of instruments may be an expandable set of surgical instruments, and/or an expandable set that includes multi-functional surgical instruments. For example, selected surgical instruments are configured to function as multiple types of instruments, e.g. the forceps may be used as forceps or may be disassembled and used as, for example, one or more retractors. Selected surgical instruments may be disassembled and combined with parts of one or more other disassembled surgical instruments. These combined parts may be referred to herein as hybrid surgical instruments. The hybrid surgical instruments may have jaw portions or different working end portions. The jaw portions or working end portions of the hybrid surgical instruments have different configurations. In addition, selected surgical instruments are multi-functional and perform the functions of multiple prior art surgical instruments. These surgical instruments may also be referred to herein as hybrid surgical instruments or multi-function surgical instruments.

In addition, the package configuration reduces the storage space required for storing the instruments because they are arranged with one or more surgical instruments being located on top of one or more other surgical instruments. In addition, because one or more of the surgical instruments are configured to perform multiple functions, less surgical instruments are required. In addition, because some of the surgical instruments are readily separable, they may be broken down to function as other surgical instruments and/or combined with other readily separable parts to form additional surgical instruments.

Multi-functional tri-view surgical instrument 160 is placed in pack 180. Suction tongue blade 140 is placed in pack 180 and extends over multi-functional tri-view surgical instrument 160. Palate retractor is placed in pack 180 and ring blade holder 130 is place in pack 180. This allows the surgical instruments to be removed from pack 180 in the order that they are needed. Ring blade holder 130 is typically removed first. Suction tongue blade 140 is removed next and secured to ring blade holder 130 to form a mouth gag. The mouth gag is connected to a suction hose (not shown) and placed in use. Hemostat 110 is removed. Palate retractor 150 is removed and placed in use with the hemostat 110. Multi-functional tri-view surgical instrument 160 and curette 170 may then be removed when needed. In addition, the Allis forceps 120 may be removed and placed into use.

The tray 102 of surgical instruments or pack 180 of surgical instruments include at least one surgical instrument that is configured for multiple tasks. In some instances, the tray or pack of surgical instruments includes at least one surgical instrument that may be readily disassembled into separate parts. For example, the tray of surgical instruments may include a hemostat or forceps that may be used as a hemostat or forceps and is readily separated into separate pieces wherein one or more of the two separate pieces may be used individually as a retractor. In some instances, the tray 102 or pack 180 of surgical instruments includes at least two instruments, wherein the first surgical instrument may be readily separated into pieces and the second surgical instrument may be readily separated into pieces and one or more pieces of the first surgical instrument may be combined with one or more pieces of the second surgical instruments to form a hybrid surgical instrument. Thus, the surgical set is expandable.

In some instances, the tray 102 or pack 180 of surgical instruments 100 includes 10 or fewer surgical instruments. In some instances, the tray 102 or pack 180 of surgical instruments 100 includes 9 or fewer surgical instruments. In some instances, the tray 102 or pack 180 of surgical instruments 100 includes 8 or fewer surgical instruments. In some instances, the tray 102 or pack 180 of surgical instruments 100 includes 7 surgical instruments. As used in this paragraph, a multi-functional surgical instrument is counted as 1 surgical instrument. In addition, a surgical instrument that may be disassembled to form a second surgical instrument is counted as 1 surgical instrument. In addition, 2 surgical instruments that are separable and combinable to form a third surgical instrument, are counted as 2 surgical instruments.

The surgical instruments disclosed herein may be single use surgical instruments. The surgical instruments are preferably made from one or more polymers. Single use surgical instruments are preferably made from a non-metallic material. Single-use surgical instruments are preferably not made of stainless steel or surgical steel. The single-use surgical instruments may be devoid of metallic springs. The single-use surgical instruments may be devoid of screws. The single-use surgical instruments may be devoid of small parts. Small pats are parts that would fit down a person's aero digestive track. Small parts smaller than, for example, 10 millimeters. In some instances, the single-use surgical instruments are recyclable. After the surgical procedure is completed, the surgical instruments are simply placed in a container for disposal or recycling. This procedure saves valuable OR time as the surgical instruments do not need to be sprayed down and prepped to begin the sterilization process. In addition, single use surgical instruments do not need to be cleaned, inspected or sterilized after use. Accordingly, there are no costs associated with cleaning, disassembling the mouth gag, reassembling the mouth gag, inspecting and sterilizing the surgical instruments after the surgical procedure.

In some instances, one or more of the surgical instruments, as described herein, may be made of surgical steel or other conventional material and may be reusable. When the surgical instrument is readily disarticulated, it is easier to clean, inspect, repair and sterilize. Because the exemplary surgical instruments do not have small parts or do not need tools to dissemble, the cleaning and inspecting time is also greatly reduced. Furthermore, many of the surgical instruments are configured to perform multiple tasks or functions and thus, the number of surgical instruments required for a particular surgical procedure may be reduced. Thus, even when made of conventional material and reused, the surgical instruments disclosed herein reduce cost and OR time.

The flat sections 851, 852 are configured to be a needle holder 850 so that multi-functional hemostat 110 functions as a needle driver as well as a hemostat. In this exemplary embodiment, the needle holder 850 is the area along the elongated flat sections 851, 852 that extend along the angled outer portion 231 and 232 of jaws 230, 232.

Shank 208 and shank 210 are releasably coupled at releasable connector 206. Releasable connector 206 allows for the shanks 208 and 210 to be readily connected to one another and readily disconnected from one another. The releasable connector 206 is configured such that a member of a surgical staff can readily disconnect and reconnect the shanks 208, 210.

Connector 206 includes a shaft 606 (FIG. 6). A first end of shaft 606 is connected to shank 208. One or more retaining members 402 are located at the second end 222 of the shaft 606. The retaining members 402 are shown as a first lobe and a second lobe and the first lobe and second lobe are located 180 degrees from one another.

Connector 206 includes an opening 220 in shank 210. At least a portion of opening 220 has a circular cross-sectional shape. The circular cross-sectionally shaped portion is slightly larger than the diameter of the shaft 606. A second portion 404 of opening 220 is configured to be slightly larger than the one or more retaining members 402. When the second portion 404 of opening 220 is aligned with the one or more retaining members 402, the first shank 208 and the second shank 210 may be readily separated from one another by pulling the first shank 208 and the second shank 210 away from each other.

Other shapes of retaining members 402 may be used provided they allow the first and second shanks 208, 210 to smoothly pivot with respect to one another while maintaining the coupling between the first shank 208 and the second shank 210 along a first range of motion and allow for decoupling at a second point in the range of motion.

With respect to FIG. 5A, a centerline 502 extends across opening 220 and second portion 404 of opening 220. A second centerline 504 extends across shaft 606 and retaining members 402. Releasable connector 206 maintains the coupled connection between shanks 208, 210. When centerline 502 lines up with centerline 504, shank 208 and shank 210 may be separated by pulling them away from one another.

FIG. 5A illustrates a third centerline 510 that is substantially perpendicular to at least a portion of jaw 230. In some embodiments, the angle X between center line 510 and centerline 502 must be greater than 90 degrees before centerline 502 and centerline 504 line up so that the fist shank 208 and second shank 210 may be separated. In some embodiments, the angle X between center line 510 and centerline 502 must be greater than 100 degrees before centerline 502 and centerline 504 line up. In some embodiments, the angle X between center line 510 and centerline 502 must be greater than 110 degrees before centerline 502 and centerline 504 line up. In some embodiments, the angle X between center line 510 and centerline 502 must be greater than 120 degrees before centerline 502 and centerline 504 line up. In some embodiments, the angle X between center line 510 and centerline 502 must be greater than 130 degrees before centerline 502 and centerline 504 line up. In some embodiments, the angle X between center line 510 and centerline 502 must be greater than 140 degrees before centerline 502 and centerline 504 line up.

In other embodiments, opening 220 may have a substantially circular cross-section. In such an embodiment, shaft 606 may include one or more retention members (not shown) that when in an unbiased position have an outer diameter that is greater than the diameter of the opening 220 and a biased position that has an outside diameter that is smaller than the diameter of opening 220. In such an embodiment, the retention members are readily deflected radially inward to the biased position. Thus, to readily separate the two shanks from one another, a user simply deflects the retention members (not shown) and pulls them through the opening 220.

When hemostat 110 is disassembled as shown in FIG. 6, shank 208 and hook 608 may be used for other functions, such as, for example, as a retractor, elevator, trocar or other purposes. Similarly, shank 210 and hook 610 may be used as a retractor or other purpose. Thus, hemostat 110 may perform this additional function or task.

FIG. 12 is a prospective view of a mouth gag 1200. Mouth gag 1200 includes a ring blade holder 130 connected to a suction tongue blade 140. Suction tongue blade 140 and ring blade holder 130 are single use devices. They are made out of one or more polymeric materials. Ring blade holder 130 is a single piece of molded material. Ring blade holder 130 does not contain any small parts, such as, for example, springs, rivets, pins or connectors, that may separate from ring blade holder 130 and cause injury or increase OR time. Ring blade holder 130 is devoid of small separate parts, such as, for example, springs, screws, rivets and connectors. In addition, ring blade holder 130 does not require any protective covering, such as a silicon sleeve (that is commonly used on surgical steel ring blade holders) to protect a person's teeth from damage during surgery. Ring blade holder 130 includes a body 1300 (FIG. 13). Body 1300 has a ring member 1302. Ring member 1302 forms a working opening 1310. Upper portion 1306 of ring member 1302 contacts the roof of a patient's mouth and/or maxillary dentition (i.e. teeth of upper jaw) when the mouth gag 130 is used during a procedure. Ring member 1302 includes one or more optional buttresses 1280. Two buttresses 1280 are shown in the exemplary embodiment. Buttresses 1280 may provide additional strength to ring member 1302. In addition, buttresses 1280 may be configured for attachment of auxiliary devices. Such buttress configurations may include one or more flat portions. Buttresses 1280 may have various lengths and shapes and the one or more buttresses 1280may be located along one or more areas around the perimeter of the ring member 1302. Buttresses 1280, along with the ring member 1302, may be configured to provide for the placement of clips (not shown) or rings (not shown) that could be used to attach additional and/or auxiliary devices, such as, for example, lip and cheek retractors. The buttresses 1280 and ring member 1302 may allow the mouth gag 1200 to function similarly to a Dingman device (not shown). The buttresses 1280 may be configured for attaching fiber optic cables (not shown) or other devices (not shown). The attachments (not shown) may be fixed or adjustable. Ring member 1302 is configured with various curves and angles to conform with facial and oral anatomy and to allow for attachment of the pallet retractor. Ring member 1302 is configured for attachment of pallet retractor 150. Pallet retractor 150 engages ring member 1302 along portion 1390. The configuration of 1390 is a flat or horizontal section that matches the body of the palate retractor 150. The width of the pallet retractor connection member 1910 may be substantially the same as the width of portion 1390 of ring member 1302. This may increase the stability of palate retractor 150, and also facilitate in properly locating palate retractor 150. Body 1300 includes a channel 1320 for receiving a spine or shaft of suction tongue blade 140. Body 1300 includes a handle 1322 located on upper surface 1301.

Body 1300 includes a latching mechanism 1350. Latching mechanism 1350 includes a release member 1351. Release member 1351 optionally includes a plurality of ridges or knurls. An optional stop member 1351A is located below release member 1351 which prevents overtravel of the latching mechanism 1350. A channel 1360 through surface 1310 extends around three sides latching mechanism 1350 forming a flexible resilient hinge area 1362. Resilient hinge area 1362 provides a biasing force that when deflected from its resting position, biases latching mechanism 1350 toward its latching position.

Latching mechanism 1350 has an end 1352 of opposite hinge area 1362. Located on the bottom of end 1352 is a latch 1500 (FIG. 15). Latch 1500 engages with one of the catches 1640 (FIG. 16) on the spine of suction tongue blade 140 when the ring blade holder 130 is connected to suction tongue blade 140. The latch 1500 extends down low enough so that when the spine 1602 of suction tongue blade 140 is inserted in channel 1320, upward pressure is placed on latch 1500 creating deflection in resilient hinge area 1362 biasing the latch to fully engage catch 1640. To release ring blade holder 130 from tongue blade 140, release member 1351 is pushed toward surface 1301, which causes end 1352 and latch 1500 to deflect away from the catch 1640 of spine 1602 of tongue blade 140.

FIGS. 16-18 are an exemplary embodiment of a tongue blade 140. Tongue blade 140 includes spine 1602. Spine 1602 is configured to be received by channel 1320 of mouth gag 130. Tongue blade 140 has an engagement surface 1604 that engages the tongue of a patient during surgical procedures. A suction tube connector 1608 is configured to be connected to a suction hose. The body 1610 includes a hollow portion that extends from the suction tube connector 1608 to a suction inlet 1614. Engagement surface 1604 is typically sized according to the size of the patient and comes in varying sizes, see, for example, tongue blades 140, 140A and 140B (FIG. 1). An exemplary tongue blade is shown in U.S. Pat. No. 8,852,169, titled Suction Device for Evacuating Fumes, which is incorporated herein by reference in its entirety.

FIGS. 19-22B illustrate an exemplary embodiment of a palate retractor 150. Prior to the innovative palate retractor shown and described herein, surgeons will typically thread a rubber tubing through each of a patient's nasal passageways and back through the mouth and secure the rubber tubing to hold the palate/tissue out of the way. This method of retracting the palate/tissue is not optimal and can possibly displace tissue and obstruct the surgeon's view. It is also time consuming, which increases OR time and may cause irritation or bleeding in the nasal passages of the patient.

Palate retractor 150 includes a body 1900. The palate retractor is anatomically contoured to a human palate. Body 1900 has a slightly curved shape. The slightly curved shape places the upper surface 1901 of body 1900 proximate the roof a patient's mouth and provides a much better/clearer view for the surgeon and provides better options to grasp and remove tissue. As used with the description of the palate retractor 150 the term “upward” refers to portions that would be toward the roof of a patient's mouth. For example, in FIG. 22, the term upward, or upper, would refer to the direction extending up from the page, e.g. surface 1901 is an upper surface, or upward surface of body 1900. Optionally, body 1900 may be straight.

Located at a first end of body 1900 is mouth gag connection member 1910 formed by curved, or hooked member 1912. As discussed above, palate connection member 1910 is configured to match the portion 1390 of the ring member 1302. Hooked member 1912 is curved upward with respect to surface 1910 of body 1900. Hooked member 1912 is configured to, for example, couple with upper portion 1390 of ring blade holder 130 as shown in FIGS. 22A and 22B, if the mouth gag includes a ring blade holder.

Body 1900 includes a grip member 1980. Grip member 1980 includes indentations 1960 and an arcuate rib 1970. During use, grip member 1980 is configured to be gripped by a surgical instrument, such as, for example, hemostat 110, so that palate retractor 1900 may be easily manipulated during a surgical procedure. In some instances, arcuate rib 1970 may also increase the rigidity of the body 1900 proximate the ring blade holder connection member 1910.

Located on a second end of body 1900 is a palate engagement member 1920. Palate engagement member 1920 is curved upward with respect to surface 1901. Palate engagement member 1920 is curved slightly inward toward the center of body 1900. Palate engagement member 1920 is configured to wrap around the soft palate behind the uvula and elevate the palate when palate retractor is connected to ring blade holder 130 and placed in use during surgery.

Located on body 1900 proximate the palate engagement member 1920 is a pair of wings 1950, 1952. Wings 1950, 1952 are curved downward and outward with respect to surface 1901. The wings 1950, 1952 are configured to engage and hold back tonsils/soft tissue laterally during surgical procedures.

In some instances, palate retractor 150 is made of one or more polymers. In some instances, palate retractor 150 is made of a non-metallic material. In some instances, palate retractor 150 is a single use device and is disposed of after a single use.
