Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 and 2, the tendon guide device in this embodiment includes a hollow sheath 1, a handle 2 connected to the rear end of the sheath 1, and a protective sleeve 3 covering the sheath 1.

Wherein, a plurality of needle holes 11 for the suture needle to pass through are arranged on the peripheral wall of the front end of the sheath tube 1, when in operation, after the fracture end of the tendon is placed in the front end of the sheath tube 1, the operation needle and the operation line are utilized to pass through the needle holes 11, and then the fracture end of the tendon is fixed on the front end of the sheath tube 1.

In order to facilitate the insertion of the tendon fracture end into the sheath tube 1, the opening at the front end of the sheath tube 1 for inserting the tendon fracture end may be enlarged, and various means in the prior art may be adopted for the method for enlarging the opening. In addition, a notch 12 may be formed on the side wall of the front end of the sheath tube 1, and the central angle of the notch 12 relative to the peripheral wall of the sheath tube 1 may be adjusted according to the diameter of the sheath tube 1, for example, the central angle of the notch 12 relative to the peripheral wall of the sheath tube 1 may be selected within the range of 30 ° to 90 °.

The handle 2 connected with the rear end of the sheath tube 1 can be convenient for a doctor to hold during operation, and further avoid the pollution to the sheath tube 1. In the production process simultaneously, also make things convenient for the assembler to hold, and then assemble sheath pipe 1 into protective case 3 in to handle 2 is provided with bulge loop 21 with the a week connecting portion evagination of sheath pipe 1, and the diameter of this bulge loop 21 is greater than protective case 3's internal diameter, and then the insertion distance of better control sheath pipe 1 in protective case 3.

In order to conveniently and smoothly realize the assembly of the sheath 1 in the protective sleeve 3, the inner diameter of the protective sleeve 3 is matched with the outer diameter of the sheath 1, so that the sheath 1 can be inserted into the protective sleeve 3. The closed end of the protective sleeve 3 is provided with air holes 31, and the air holes 31 can effectively eliminate negative pressure generated when the sheath pipe 1 and the protective sleeve 3 are inserted and matched, so that smooth assembly of the sheath pipe 1 is ensured. In addition, after the disinfected sheath tube 1 is assembled in the protective sleeve 3, the protective sleeve 3 can further prevent the sheath tube 1 from being polluted, and the sanitation degree of the sheath tube 1 is improved. The assembled sheath tube 1 and the protective sleeve 3 can be packaged, and can be used as disposable consumables after being sterilized when in use, thereby ensuring the sterile operation of the operation process.

In addition, in order to reduce the damage to other tissues during the insertion of the sheath tube 1, the side wall of the front end of the sheath tube 1 is curved radially inward in an arc shape in this embodiment. In order to insert the sheath 1 into the tendon-retracted position more easily, the sheath 1 is a tube body that is bent in the axis and can be deformed slightly. The axis of the sheath 1 curvature can match the curved path into the body, better reaching the tendon rupture. And the characteristic of small deformation can be adapted to the small deformation of the sheath tube 1 in the entering process.

The utility model provides a tendon guiding device, only set up the pinhole 11 that supplies fixed tendon at the front end of a sheath 1 can, during the use, take out sheath 1 self preservation protective sleeve 3, penetrate sheath 1 from tendon fracture department internal again, and then penetrate the front end of sheath 1 and contract back the department of tendon fracture end, put into the fracture end of tendon in the front end of sheath 1 through other appurtenance again, utilize the operation line to pass pinhole 11 and realize the fixed of tendon fracture end at sheath 1 front end. And then the sheath tube 1 is pulled back, so that the tendon rupture end is pulled back to the tendon rupture position, and the subsequent tendon repair operation is conveniently carried out by a doctor. The tendon guide device has the advantages of simple structure and low cost, can be used as disposable consumables, and does not need to be sterilized after use. And the tendon guide device is used for realizing the resetting treatment of the retracted tendon, so that the operation is simple and the operation of a doctor is convenient.
