1. Field of the Invention
The present invention relates to a medical instrument holding or supporting apparatus, and more particularly to a medical instrument holding or supporting apparatus including an improved or simplified structure or configuration that may be easily and quickly made or manufactured by the manufacturers and that may be adjusted to different length for conducting different medical surgery or medical operation.
2. Description of the Prior Art
Typical medical instruments, such as rigidoscopes, laparoscopes, endoscopes, trocars, treating instruments, or the other medical instruments or the like have been developed and widely provided and used for conducting or operating an operation on a patient, and are typically grasped and held by the hands of the operators, such as the doctors, and it will be difficult for the operators or the doctors to hold the medical instruments and to conduct or operate the operation on the patient.
Normally, the medical instruments are grasped and held by one of the operators or the doctors, and the other operator or doctor will stand beside the medical instruments holding operator and will both standing near the patient at the same time, in a tiny or narrowed operation room.
For allowing the medical instruments to be held in place without being grasped by the operators or the doctors, a scope-holder has been disclosed and used to hold the medical instruments in place, for inserting the medical instruments into the abdominal cavity of a patient.
For example, U.S. Pat. No. 5,697,939 to Kubota et al. discloses one of the typical medical instrument holding apparatuses comprising a plurality of arms sections and holding sections for holding and grasping the treating instrument or medical instrument and for engaging or inserting the treating or medical instruments into the abdominal cavity of the patient.
However, the typical medical instrument holding apparatuses comprise a rather complicated structure or configuration having a number of parts or elements that may not be easily and quickly made or manufactured and that may not be easily used to conduct the operation on the patient.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional medical instrument holding apparatuses.
The primary objective of the present invention is to provide a medical instrument holding or supporting apparatus including an improved or simplified structure or configuration that may be easily and quickly made or manufactured by the manufacturers and that may be adjusted to different length for conducting different medical surgery or medical operation.
In accordance with one aspect of the invention, there is provided a medical instrument holding apparatus comprising a housing including a chamber formed therein, a shaft slidably engaged into the chamber of the housing and movable into and out of the chamber of the housing, the shaft including an anchoring member provided thereon, the housing including a guiding member extended into the chamber of the housing and engaged with the shaft for guiding and limiting the shaft to slide relative to the housing only and for preventing the shaft from being rotated relative to the housing, a locking device including a bore formed therein for slidably receiving and engaging with the shaft, and the locking device including a positioning member for selectively engaging with the anchoring member of the shaft and for locking the shaft and the housing together, and at least one fastener engaged with the housing and the locking device for locking the locking device to the housing and for securing the shaft and the housing together with the locking device.
The anchoring member of the shaft is selected from an outer thread. The positioning member the locking device is selected from an inner thread for selectively engaging with the outer thread of the shaft. A gripping mechanism may further be provided and disposed on a free end portion of the shaft.
A supporting mechanism may further be provided and includes a supporting arm having a pivot member, the housing is provided on the pivot member of the supporting arm. The supporting mechanism includes a base, and the supporting arm includes a lower portion rotatably attached on the base with a pivot device, and the pivot member is provided or attached on an upper portion of the supporting arm.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
Referring to the drawings, and initially to
The supporting arm 20 further includes another pivot device or joint or member 23 formed or provided or disposed or engaged on the upper portion 24 of the supporting arm 20 and arranged to be pivoted or rotated relative to the supporting arm 20, the pivot member 23 includes a sleeve or cylindrical or tubular element or barrel or housing 25 provided or attached or extended forwardly therefrom and arranged or extended along the X-axis, for example. The housing 25 includes a bore or chamber 26 formed therein, and includes a longitudinal guiding flange or rib or member 27 extended into the chamber 26 of the housing 25 (
A follower or sliding member or shaft 30 is engageable with or into the chamber 26 of the housing 25 and movable or adjustable relative to the housing 25 and movable or slidable into and out of the chamber 26 of the housing 25, and includes a longitudinal guiding groove or channel or element 31 formed in the outer peripheral portion thereof for slidably receiving or engaging with the longitudinal guiding member 27 of the housing 25 and for guiding or limiting the shaft 30 to slide or move relative to or along the housing 25 and for preventing the shaft 30 from being pivoted or rotated relative to the housing 25, and includes a positioning or retaining or anchoring member 32, such as an outer thread 32 formed or provided thereon, and includes a holding or grasping or gripping mechanism 33 formed or provided or disposed on the outer or free end portion 34 of the shaft 30 and provided for holding and grasping a treating or medical instrument (not illustrated).
For example, the treating or medical instrument may be selected from a rigidoscope, laparoscope, endoscope, trocar, treating instrument, or the other medical instruments. However, the treating or medical instrument is typical and is not related to the present invention and will not be described in further details. The treating or medical instrument holding or grasping or gripping mechanism 33 is thus formed or provided or disposed on or extended from the outer or free end portion 34 of the shaft 30 and moved in concert with the shaft 30 relative to the housing 25, and arranged for allowing the shaft 30 and the gripping mechanism 33 and thus the treating or medical instrument to be moved or adjusted toward or away from the housing 25.
The medical instrument holding or supporting apparatus in accordance with the present invention further comprises a latching or anchoring or retaining or positioning or locking ring or device 40 including a chamber or bore 41 formed therein for slidably receiving or engaging with the shaft 30 and for allowing the locking device 40 to be slidably attached or engaged onto the shaft 30, and the locking device 40 is selectively locked or secured or fastened to the housing 25 with latches or bolts or screws or fasteners 42 or the like. The locking device 40 further includes another anchoring or retaining or positioning member 43, such as an inner thread 43 formed or provided therein for selectively engaging with the outer thread 32 of the shaft 30 and for selectively latching or anchoring or retaining or locking or positioning or securing the shaft 30 and the housing 25 together with the locking device 40.
In operation, the longitudinal guiding member 27 of the housing 25 is slidably received or engaged in the longitudinal guiding channel or element 31 of the shaft 30 for guiding or limiting the shaft 30 only to slide or move relative to or along the housing 25 and for preventing the shaft 30 from being pivoted or rotated relative to the housing 25, and thus for allowing the shaft 30 and the gripping mechanism 33 and thus the treating or medical instrument to be moved or adjusted toward or away from the housing 25 selectively (
It is to be noted that the adjustable or sliding engagement or attachment mechanism or structure or configuration of the shaft 30 relative to the housing 25 allows the gripping mechanism 33 and thus the treating or medical instrument to be supported at different location or position for conducting different medical surgery or medical operation. Alternatively, as shown in
Accordingly, the medical instrument holding apparatus in accordance with the present invention includes an improved or simplified structure or configuration that may be easily and quickly made or manufactured by the manufacturers and that may be adjusted to different length for conducting different medical surgery or medical operation.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
