Abstract

The present invention relates to an endoscopic apparatus for a surgical operation, which comprises: an outer cover (12) having an internal fluid passage; a grippable handle (16) which is elongated along the axial line of the handle and has an upper end part and a lower end part when the axial line of the handle is vertical; a coupling (14) which is placed adjacently to the lower end part of the handle, firmly connects the handle to the outer cover in a middle position along the length of the outer cover and slopingly maintains the outer cover with respect to the axial line of the handle; and a protruding part (86a) extended horizontally from a position adjacent to the upper end part of the handle in order to be interlocked with a part of the hand of a surgeon to support the endoscopic apparatus when the surgeon does not tightly grip the handle with the hand.

Description

[0001] ENDOSCOPE APPARATUS FOR OPERATION [0002]

The present invention relates to a surgical endoscope apparatus.

The endoscope is inserted into the patient's nostril and allows the surgeon to observe the enlarged image of the surgical site with a monitor connected to the video camera attached to the endoscope. Nose / bronchial surgery is performed on a limited area where the vascular system is developed. Therefore, during surgery, blood and surgical tissue debris are frequently attached to the endoscope. It is important to remove blood and surgical tissue debris from the endoscopic lens in order to be able to observe the surgical site optimally. Normally, this is done by moving the lens of the endoscope, or by pulling the endoscope out of the nostril and hand-washing it.

The patient usually lies straight under general anesthesia. The endoscope is inserted into the nostril and manipulated to position the tip of the endoscope near the surgical site. Endoscopes are typically manipulated by the surgeon using finger forces to adjust the position of the endoscope against the forces exerted by the tissue structure and the attachment device of the endoscope, such as video camera heads and cables, fiber optic transmitters, do. This method of dealing with endoscopes is known to cause fatigue, especially in long operations.

Another problem encountered in conventional surgery using endoscopes is the cumbersome working space. Conventional methods of manually manipulating the endoscope can limit the working space around the endoscope for manipulation of other devices. This inconvenience is increased if there is cross-tube treatment near the nostril opening and / or hand work that is difficult to handle. The current pump-driven pedal system has foot-operated controls. Placing these controls among other devices, such as electrosurgical instruments and power-assisted cutting devices, causes the surgeon during surgery to be mentally confused because the surgeon must move to position the multiple controls. These devices are also cumbersome to install and generally do not provide adequate fluid volume and pressure.

SUMMARY OF THE INVENTION The object of the present invention is to solve the above problems, and it is a main object of the present invention to provide a surgical instrument,

And an ergonomically superior gantry system for use in other surgical procedures.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, and it is a main object of the present invention to provide an ergonomically excellent gantry system for use in copper surgery and other surgeries requiring inhaling and / or inhalation.

An endoscope of the present invention is a surgical endoscope apparatus comprising: an envelope (12) having an inner fluid passage; A gripable handle (16) having a top and bottom end that is elongated along a handle axis and when the handle axis is vertical; A coupling positioned adjacent a lower end of said handle and coupling said handle to said shell in an intermediate position along the length of said shell and holding said shell at an angle relative to said handle axis; And a protrusion 86a extending laterally from a position adjacent the upper end of the handle to support the endoscope device in engagement with a portion of the surgeon's hand when the surgeon's hand is not holding the handle securely.

The surgical endoscope device according to the present invention eliminates the need for the surgeon to hold the endoscope device by hand along the endoscope axis in a conventional manner so that the placement and manipulation of other devices It is possible to secure a wide space.

Figure 2 is a right side view of the handle and valve assembly.
Figure 3 is a left side view of the handle and valve assembly

1, the endoscope apparatus 10 includes an endoscope shell 12 held within a coupling 14 connected to a lower end of a long handle 16. The endoscope apparatus 10 includes an endoscope 12, The endoscopic sheath 12 includes an elongated hollow tube 18 having an opening in the distal end 20.

A fitting 22 having an opening 24 into which an endoscope can be inserted is provided at the proximal end of the endoscope shell. The endoscope used in this endoscope apparatus usually includes an eyepiece 27, or alternatively, a miniature television camera (not shown).

The eyepiece or camera is connected to the proximal end of the shaft 25 and is positioned within the shaft 25 at the tip of the endoscope 20 to be positioned at the distal end 20 of the tube 18 when the endoscope is fully assembled A lens system is arranged to focus the enlarged image of the adjacent surgical site on an eyepiece or a television camera.

Fiber optic transmission systems are usually installed in the shaft to illuminate the surgical site.

The endoscope has a projection 31 cooperating with a detent (not shown) of the opening 24 to secure the endoscope in place in the shell 12. [

Immediately below the fitting 22 near the proximal end of the shell 12 is a nut 26 which is rotatable but is restricted in axial movement along the shell. This nut can be engaged with the threaded portion 28 of the coupling 14, which allows the shell to be removed for replacement.

The envelope can be rotated about the shell axis within the coupling 14 and secured by the nut 26 in any desired rotational position. Therefore, the side observation endoscope fixed within the sheath can be oriented at any desired angle to observe the surgical site on the side of the endoscope axis.

Beneath the nut is a tapered element 30, which is axially spaced apart and includes upper and lower frusto-conical features 30a, 30b. The tapered element is fluid-tightly engaged with O-rings 31a, 31b serving as seals.

The O-ring is located in the annular recess of the tapered hole 33 extending through the coupling 14. A slot 32 located on a narrow portion of the sheath between the upper frusto-conical portion 30a and the lower frusto-conical portion 30b includes a fluid passage 35 extending through the interior of the sheath 12 and the adapter 34 Which adapter 34 is threaded into the wall of the coupling and fastening the coupling 14 to a selected one of the fittings 38, 40 with threaded portions at the lower end of the handle And a collar 36 formed with an internally threaded portion.

The unused threaded fitting is closed by the cap 42. The adapter 34 is provided with a collar 44 having a pair of protrusions 45 engageable with a pair of opposed recesses selected from the recesses formed in the end face of the fitting 38.

In Figure 3, twelve such recesses 46 are shown on the end face of the fitting 40 (the fitting 38 has similar recesses). By the engagement of the recess and the protrusion, the coupling can be fixed at any one angle selected from twelve discontinuous angles with respect to the axis of the handle 16.

In this embodiment, the angle of the endoscope relative to the longitudinal axis of the handle is limited to twelve discontinuous angles. The slot 32 of the tapered element 30 is preferably located adjacent the proximal end of the tube 18 to maximize the length of the tube portion that can be inserted into the nasal cavity without requiring an overly long endoscope.

The fact that the coupling is located on the side of the handle allows the valve to be positioned within the handle rather than in an assembly aligned with the endoscope axis.

This configuration allows the use of relatively short couplings and contributes to maximizing the working length of the endoscope.
