In order to realize the purpose, the utility model discloses a technical scheme is:
the utility model provides an integrated apparatus of guide pin and triangle-shaped scalpel area switch in arthroscope entry which characterized in that: the handle is in a long flat shape, the reamer is in a triangular shape, the handle and the reamer are integrally molded, a guide pin hole is axially arranged in the handle and the reamer in a penetrating manner, a guide pin is sleeved in the guide pin hole, a press switch is arranged on the handle and is communicated with the middle of the guide pin hole, the press switch is used for clamping and fixing the guide pin, and a cutting edge is arranged at the bottom end of the reamer;
the inner wall of press switch and metal spring leaf tail end fixed connection, the middle part and the control button fixed connection of metal spring leaf, the top of metal spring leaf sets up first clamping piece, set up the second clamping piece in the press switch, its position with first clamping piece is corresponding, first clamping piece reaches the second clamping piece supplies to press from both sides the clamp and fix the guide pin.
The arthroscope is guided in the way and integrated apparatus with switch of triangle scalpel, wherein: the cutting edge is a triangular scalpel and is provided with edges at two sides.
The arthroscope is guided in the way and integrated apparatus with switch of triangle scalpel, wherein: the metal spring plate has elasticity for recovering the initial state.
The utility model has the advantages that: with guide pin and triangle-shaped scalpel integration, when simplifying arthroscope approach and establishing the method, guaranteed that the guide pin does not leave the art district, make the art person can see the setpoint always, can guarantee again that the direction of sharp sword and guide pin are same pore, same direction, realize quick, accurate location, and because the switch can fix the guide pin, thereby guaranteed to cut into the degree of depth accurate, also can lead to take the guide pin and take out together when the apparatus is taken out, avoid the guide pin to leave over internally. The instrument can increase the accuracy of the operation, reduce the operation trauma and save the operation time, so that the arthroscopic operation is more in line with the minimally invasive idea and the quick rehabilitation surgical idea.

Detailed Description
As shown in fig. 1 to 4, an integrated instrument with a switch for a guide pin and a triangular scalpel in an arthroscopic approach is characterized in that: the handle 1 is in a long flat shape, the reamer 3 is in a triangular shape, the handle 1 and the reamer 3 are integrally formed, a guide pin hole 4 is axially arranged in the handle 1 and the reamer 3 in a through mode, the guide pin hole 4 is sleeved into a guide pin 10, a press switch 2 is arranged on the handle 1, the press switch 2 is communicated with the middle of the guide pin hole 4, the press switch 2 is used for clamping and fixing the guide pin 10, and a cutting edge 5 is arranged at the bottom end of the reamer 3.
Inner wall and the 7 tail end fixed connection of metal spring leaf of press switch 2, the middle part and the 6 fixed connection of control button of metal spring leaf 7, the top of metal spring leaf 7 sets up first clamping piece 8, set up second clamping piece 9 in the press switch 2, its position with first clamping piece 8 is corresponding, first clamping piece 8 reaches second clamping piece 9 supplies to press from both sides the clamp to be fixed guide pin 10.
The cutting edge 5 is a triangular scalpel and is provided with edges at two sides.
The metal spring piece 7 has elasticity for restoring the initial state.
In the embodiment, after the arthroscope observation approach is built, the guide pin 10 is firstly used for positioning in order to build the working approach, after the guide pin 10 is positioned and determined, the guide pin 10 is not pulled out, the handle 1 is held by hand, the guide pin hole channel 4 is sleeved into the guide pin 10, the entering point and the depth of the cutting edge 5 are observed through the arthroscope, as the direction and the angle are determined through the guide pin 10, the cutting edge 5 only needs to be inserted into a joint cavity along the direction and the angle determined by the positioning guide pin, the reamer 3 is inserted into the hole along the cutting edge 5 for reaming the working approach, after the working approach meets the surgical requirements, the press switch 2 is communicated with the middle part of the guide pin hole channel 4, the press switch 2 is pressed, and the control button 6 drives the top end of the metal spring piece 7 and the first clamping piece 8 to move, the first clamping piece 8 and the second clamping piece 9 clamp and fix the guide pin 10 together, at this time, the device is pulled out and pulled out together with the guide pin 10, the push switch 2 is loosened, the metal spring piece 7 has elasticity and can automatically recover to an initial state to drive the control button 6 and the first clamping piece 8 to move, the first clamping piece 8 and the second clamping piece 9 loosen the guide pin 10 together, the guide pin 10 can be taken out from the guide pin duct 4, at this time, the working access is established, and arthroscopic surgery can be carried out.
