The embodiment of the utility model provides a working sleeve with a guiding function, which comprises a bracket 3, a first sleeve 2 and a second sleeve 1, wherein the first sleeve 2 is arranged on the bracket 3, and the second sleeve 1 is arranged on the bracket 3. The working sleeve with the guiding function can combine the endoscope and the surgical instrument to be arranged, so that the endoscope is ensured to be fixed, and the movement of the surgical instrument is not interfered.

The bracket 3 is used as the main body of the utility model and is arc-shaped, and the center of the arc is positioned at the front end part of the first sleeve 2. Because the second sleeve 1 is arranged on the bracket 3, the arc shape can conveniently lead the second sleeve 1 on the bracket 3 to intersect with the guiding direction of the first sleeve 2. The arc-shaped circle center is arranged at the opening of the front end of the first sleeve 2, so that the guide directions of the second sleeve 1 and the first sleeve 2 can be conveniently intersected at the circle center, namely the position of the front end part of the first sleeve 2 for operation.

The bracket 3 is provided with a through hole 6, the through hole 6 is used for detachably placing the second sleeve 1, the through hole 6 has a guiding effect on the second sleeve 1, the central lines of the through holes 6 are converged at one point, and the converged point is the front end operation position of the first sleeve 2. The through holes 6 are arranged at intervals, the position of each through hole 6 on the bracket 3 is different, and the position or the angle of the second sleeve 1 can be different when the second sleeve 1 is placed through the different through holes 6, so that the endoscope passing through the second sleeve 1 can adopt various positions or angles, and can be adjusted according to the needs of actual conditions in use.

The through holes 6 are arranged at the same interval, and the angles which can be arranged on the second sleeve 1 are uniformly distributed in the angle corresponding to the circular arc of the bracket 3 as much as possible by arranging the through holes at equal intervals.

The central line of the through hole 6 is in a plane with the central line of the first sleeve 2, so that the second sleeve 1 or the endoscope in the through hole 6 can be accurately aligned with the working position of the surgical instrument. The center line of the through hole 6 passes through the center of the bracket 3, so that the endoscope is further ensured to be accurately aligned with the working position of the surgical instrument, namely the center of the bracket 3.

The diameter of the inner surface of the through hole 6 is set to be larger than the outer diameter of the second casing 1, which ensures that the second casing 1 can smoothly pass through the through hole 6 without obstruction.

The sealing rings 4 are arranged in the through holes 6, the sealing rings 4 are annular, specifically, the sealing rings 4 can be made of nontoxic and harmless soft materials such as medical rubber, and the sealing rings are rubber rings. The outer surface of the sealing ring 4 is in contact fit with the inner surface of the through hole 6, when the second sleeve 1 is installed, the outer wall of the second sleeve 1 is in contact with the inner surface of the sealing ring, so that the effect of blocking a gap between the second sleeve 1 and the through hole 6 is achieved, the sealing effect is achieved, and the sealing device is more sanitary and safer.

Each through-hole 6 is inside all to set up spacing collar 5, and spacing collar 5 is cyclic annular, and the surface and the 6 internal surface contact cooperations of through-hole of spacing collar 5 to, 5 one end contact sealing washer 4 of spacing collar. The limiting ring 5 can facilitate the installation of the sealing ring 4 and can also prevent the sealing ring 4 from falling out of the through hole 6.

Specifically, the inner surface of the through hole 6 can be set to be stepped, the diameter of the first inner surface close to the front end of the first sleeve 2 is smaller than the diameter of the second inner surface far away from the front end of the first sleeve 2, when the sealing ring 4 is installed, the end surface of the sealing ring 4 can be tightly attached to the convex part of the inner surface of the through hole 6, the position of the sealing ring 4 can be effectively fixed, and the sealing ring 4 is prevented from falling off.

On the support 3, keep away from one side of each through-hole 206 and set up first hole alone, the internal diameter in first hole is corresponding with the external diameter of first sleeve pipe 2, and the effect in first hole is for setting up first sleeve pipe 2 on support 3, guarantees that first sleeve pipe 2 installation rear end and rear end link up.

The second sleeve 1 comprises a pipe body and a handle, and the handle is arranged at the rear end of the pipe body. The handle is of a plate-shaped structure, the area of the surface of the handle is larger than the area of a pattern formed by the surrounding of the outer wall of the pipe body, the surface is provided with a second hole, the shape formed by the surrounding of the inner wall of the second hole corresponds to the shape formed by the surrounding of the inner wall of the pipe body, and the front end and the rear end of the second sleeve pipe 1 formed after connection are ensured to be communicated.

Specifically, the handle and the tube body may be integrally formed, or for ease of manufacture, the handle and the tube body may be two separate parts, fixedly connected.

In use, the physician can easily insert the second cannula 1 into any one of the through holes 6 of the holder 3 by holding the handle with the physician, so that the second cannula 1 is in a different position. The handle can make the convenient handheld of second sleeve pipe 1, avoids directly handheld body, pollutes the body, and then pollutes the operation environment when the body stretches into through-hole 6. At the same time, the second sleeve 1 is prevented from sliding out of the bracket 3, and when the second sleeve 1 slides down, the handle will block the bracket 3 and prevent it from further separating from the bracket 3.

The front end of the tube body is provided with a chamfer, the inside of the tube body is used for arranging an endoscope, and the endoscope passes through the tube body to reach a surgical position so as to perform surgery.

First sleeve pipe 2 sets up on support 3, and support 3 and first sleeve pipe 2 can integrated into one piece make, for the convenience of making, also can divide into two parts to the rear end fixed connection of first sleeve pipe 2 is on support 3. The surgical instrument passes through the first sleeve 2 and finally reaches the position of a patient needing surgery, so that the accommodating space of the surgical instrument is relatively independent, the interference of other objects on the surgical instrument is eliminated, and the stability of the surgery is improved.

First sleeve pipe 2 is provided with the handle, plays the effect that makes things convenient for the doctor to grip, specifically, the handle can set up alone at first sleeve pipe 2 rear end, also can not set up alone and regard support 3 as the handle, and the demand that grips can all be satisfied to two kinds of modes.

The front end of the first sleeve 2 is provided with an avoidance area, the avoidance area is positioned on the side wall of the first sleeve 2, and the avoidance area can remove a tube body part blocking the view of the endoscope in the extending direction of the endoscope, so that a good view in the operation process is ensured.

Specifically, the avoiding region may be a notch, and the notch is obliquely arranged relative to the length direction of the first casing 2, at this time, the notch may cover the entire circumference of the first circular tube 2, or may cover a part of the circumference, or the avoiding region may be a notch parallel to the center line of the first casing 2. The first tube 2 ensures that the cut-out cuts off the first sleeve 2 during installation as a part that is close to the second sleeve 1 and blocks the view of the endoscope. After the surgical instrument passes through the first sleeve 2, a doctor needs to observe the surgical condition from the upper side, an incision is formed, so that the doctor can conveniently observe the surgical condition, and meanwhile, a larger space is reserved for the endoscope due to the existence of the incision, so that the endoscope is convenient to install and use.
