20120289976
The present invention relates to a surgical device and a medical needle module having an indication function. More particularly, the present invention relates to a technique for enabling a medical needle or a surgical device used by a practitioner such as doctor or the like to perform an indication function during a medical practice.
A medical needle is used for various purposes. That is, medical needles range from a surgical needle used together with a suture in order to suture tissues such as serosae, muscles, fasciae, skin, blood vessels or the like of a human body to a needle used for various medical practices, various medical assistant practices, blood-gathering and the like by pressing, pricking, or penetrating a part of a patient's or an animal's body.
Conventionally, in using a medical needle, especially in using the medical needle in the body, it is a fact that the position of a body part with which the medical needle is to be brought into contact is estimated and adjusted, or the part in which the medical needle has been used is examined again, totally depending on the practitioner's eye measurement. Thus, when the practitioner lacks experience or makes a mistake, a medical needle may be erroneously used, causing problems such that the medical practice is prolonged in a simple case and an emergency occurs in a serious case.
Therefore, in order to address the above problems, the inventor of the present application has devised a medical needle module and a surgical device having an indication function, and thus proposes them through the present disclosure.
It is, therefore, an object of the present invention to solve all the aforementioned problems of the prior art.
It is another object of the present invention to provide a novel medical needle module capable of allowing a medical needle to be precisely used.
It is still another object of the present invention to provide a novel surgical device capable of allowing a medical needle to be precisely used.
It is still another object of the present invention to allow a required indication to be carried out on a body part during a surgical operation.
In accordance with the present invention, a novel medical needle module capable of allowing a medical needle to be precisely used is provided.
In accordance with the present invention, a novel surgical device capable of allowing a medical needle to be precisely used is provided.

Hereinafter, various preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that a person skilled in the art can easily practice the present invention.
As shown in
First, the medical needle 110 in accordance with an embodiment of the present invention may have a linear shape as illustrated or may have a slightly curved shape. The medical needle 110 may be made of various materials such as metal, e.g., stainless steel, wood, a synthetic resin, rubber, ceramic, or the like.
The medical needle 110 in accordance with an embodiment of the present invention may include a tip portion and a body part extended from the tip portion and including the light channel unit 120 therein as illustrated. In consideration of certain stiffness that is generally required for the medical needle 110, it is preferred that the medical needle 110 may have a section width of the thickest portion surrounding the light channel unit 120 ranging from about 0.5 mm to 1.5 mm, which may be different depending on the materials. Of course, for good penetration characteristics, it is preferred that the medical needle 110 may be configured to taper toward the tip portion such that a section width of a lower portion is smaller than that of an upper portion.
Next, the light channel unit 120 in accordance with an embodiment of the present invention will be described. The light channel unit 120 may serve to provide a path to the tip portion 140 (i.e., to the interior of the tip portion of the medical needle 110) to light irradiated from the light irradiation unit 130 as illustrated such that the light irradiated from the light irradiation unit 130 is cast upon a body part requiring a light indication in accordance with the present invention. Preferably, the interior of the light channel unit 120 may be coated with a material (e.g., a known light transmissive material or an optical fiber material) advantageous for light reflection in order to cope with such situation that the light irradiated from the light irradiation unit 130 has poor straightness. More preferably, the tip portion 140 of the light channel unit 120 may further include a condensing lens (not shown) to enhance the straightness of light irradiated from the light channel unit 120 to the outside. The condensing lens may be a focusing lens or a collimator.
Finally, the light irradiation unit 130 in accordance with an embodiment of the present invention will be described. The light irradiation unit 130 may perform a function of generating light from electrical energy and irradiating light. Preferably, such light may be a type of light appropriate to be irradiated to the outside through the light channel unit 120 (e.g., laser light) due to its excellent straightness. Thus, the light irradiation unit 130 may include a known laser pointer (not shown).
The laser pointer is a device for irradiating bright light to a certain portion having a small area to indicate or highlight the corresponding portion. The laser pointer is a device capable of emitting visible colored light having high straightness with only a small output power ranging from about 5 mW to 1000 mW. Thus, the laser pointer may be appropriate for a practitioner or the like to properly observe the light having such a small power as not to harm a body part (especially a weak part of a human body). Various known laser pointers may be applied to the present invention without limitation, and most preferably, a low-priced DPSS laser pointer employing an infrared diode laser module (not shown) may be applied to the present invention. In particular, when the color of light from the DPSS laser pointer is green or blue, the practitioner can accurately recognize a light-irradiated portion without being confused with a tissue or blood observed by the practitioner.
The configuration of the medical needle module 100 in accordance with the present embodiment is similar to that described in the first embodiment. In this embodiment, however, it should be noted that a diffraction unit 150 is further disposed in the tip portion 140 of the light channel unit 120. As illustrated, the diffraction unit 150 may include two or more diffraction slits 155.
Also, according to the present embodiment, light from the light irradiation unit 130 may be irradiated to the outside through the tip portion 140 after passing through the light channel unit 120. Here, such light may pass through the diffraction slits 155 of the diffraction unit 150 and show a certain indication pattern (a diffraction pattern) on the body part to which the light is irradiated.
Preferably, the diffraction unit 150 may be configured to be detachably attached to the tip portion 140. Thus, the practitioner may see a desired indication pattern by replacing the diffraction unit 150 when he/she wants.
Further, the diffraction unit 150 may have a slit pattern to show a two-dimensional indication pattern, rather than one-dimensional indication pattern. Typically, such a slit pattern may be a pattern having a circumferential shape, a concentric circular shape, or a lattice shape.
In accordance with the present embodiment, when the practitioner uses the medical needle 110 in suturing or the like, he/she may compare and check the interval of the needle stitches already sutured by him/her with the interval of the indication pattern. In other cases, when the practitioner uses the medical needle 110, he/she may accurately measure a distance between a body part indicated by the medical needle 110 and another body part.
As illustrated, the indication module 200 in accordance with an embodiment of the present invention may include a plurality of indication units 210 and a medical needle module guide 220.
First, the plurality of indication units 210 in accordance with an embodiment of the present invention may be preferably embedded in the medical needle module guide 220 at regular intervals as illustrated. Each of the plurality of indication units 210 may include a light irradiation unit (not shown) similar to that described in the first embodiment. Further, preferably, each light irradiation unit may be slightly inclined in a direction indicated by the medical needle 110 in order to irradiate light close to the body part indicated by the medical needle 110.
Meanwhile, the medical needle module guide 220 in accordance with an embodiment of the present invention may have a guide structure for guiding the medical needle module 100. Thus, the medical needle module 100 may be configured to move along the medical needle module guide 220 on the body part in which the medical needle module 100 can be used. For example, the medical needle module 100 may further include a wheel (not shown) or a slider (not shown) for such movement.
Finally, it should be appreciated that, in configuring the surgical device in accordance with the present embodiment, an ordinary needle which does not have such an indication function may also be employed in place of the medical needle module 100.
Meanwhile, the inventor of the present application has invented various novel suturing apparatuses using a surgical needle as one of primary components, and such suturing apparatuses may have been already disclosed or will be disclosed in Korean Patent Application No. 2009-37128, PCT International Application No. PCT/KR2009/003419, PCT International Application No. PCT/KR2010/005851, PCT
International Application No. PCT/KR2010/005852, and PCT International Application No. PCT/KR2010/006448 (each of the disclosures of the above applications should be regarded as being incorporated herein by reference in its entirety). The inventor of the present application submits that the foregoing suturing apparatuses can be considered as examples of the apparatuses which use the medical needle module or the surgical device in accordance with the present invention.
As shown in
The indication pattern P may be variably formed according to the slit patterns of the diffraction unit 350. For example, the indication pattern P may be a pattern P for guiding zigzag suturing as mentioned in the PCT International Application No. PCT/KR2009/003419. Of course, various patterns may be formed to guide suturing other than that mentioned in the PCT International Application No. PCT/KR2009/003419.
In accordance with an application of the present invention, the medical needle module or the surgical device in accordance with the present invention may be employed as a component of a surgical robot system (not shown) increasingly used for various operations. That is, the surgical robot system including the medical needle module or the surgical device in accordance with the present invention may have a reinforced indication function capable of enhancing convenience of practitioners or safety of operations.
