Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a coronary artery shunt embolism forceps. Background Art

[0002] During coronary artery bypass grafting, a small incision is first made in the coronary artery longitudinally as an anastomosis site. In order to ensure that the coronary artery beyond the incision still has blood supply during the off-pump bypass surgery, a shunt plug needs to be placed in the coronary artery cavity. The shunt plug is a hollow straight cylindrical structure, and the coronary artery on the surface of the heart has a certain physiological curvature. Therefore, during the placement process, the shunt plug often needs to be bent to a certain degree so that both ends can enter the coronary artery cavity.

[0003] Currently, conventional bypass forceps are used to place shunt plugs. It is difficult to control the curvature of the shunt plug and it is not easy to stabilize it. Therefore, the process of placing the shunt plug has always been one of the difficulties and dangers of coronary artery bypass surgery. This difficulty can only be overcome by relying on the surgeon's long-term training and experience.

[0004] Coronary artery bypass grafting is a very delicate surgical operation. In the existing technology, ordinary bypass forceps are used to control the angle of the shunt plug. The operation is very difficult and requires the operator to use two forceps at the same time and cooperate skillfully to complete it. If the operation time is too long, the patient may suffer a heart attack during the operation. This is often the most distressing process of the entire operation. Summary of the invention

[0005] To this end, the present invention provides a coronary artery shunt plug forceps to solve the problem of great difficulty in controlling the angle of the shunt plug caused by ordinary bypass forceps in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] Furthermore, an angle is set between the fork head and the end of the upper handle, and an angle is set between the elbow and the end of the lower handle.

[0009] Furthermore, the angle between the fork head and the end of the upper handle is 90°, and the angle between the elbow and the end of the lower handle is 90°.

[0010] Furthermore, there is a smooth transition between the fork head and the end of the upper handle, and there is a smooth transition between the elbow and the end of the lower handle.

[0011] Furthermore, the curved shape of the forked head is symmetrically arranged with respect to the longitudinal plane where the elbow is located.

[0012] Furthermore, the bifurcated head is any one of a semicircular arc shape, a U shape or a V shape.

[0013] Furthermore, the fork head and the upper handle are made of stainless steel in one piece, and the elbow and the lower handle are made of stainless steel in one piece.

[0014] Furthermore, the fork head is detachably arranged on the upper handle, and the elbow is detachably arranged on the lower handle.

[0015] Furthermore, it also includes an upper sleeve and a lower sleeve, the upper sleeve is connected to the fork head, the upper sleeve is plugged into the upper handle, the lower sleeve is connected to the elbow, and the lower sleeve is plugged into the lower handle.

[0016] Furthermore, both the upper sleeve and the lower sleeve are provided with a slot, and both the upper handle and the lower handle are provided with a snap-on column. The slot of the upper sleeve is snap-fitted with the snap-on column of the upper handle, and the slot of the lower sleeve is snap-fitted with the snap-on column of the lower handle.

[0038] Example 2

[0039] like Figures 6 to 8 As shown, a coronary shunt embolization forceps in this embodiment includes all the technical features of Example 1. In addition, an angle is set between the fork head 3 and the end of the upper handle 1, and an angle is set between the elbow 4 and the end of the lower handle 2; the angle between the fork head 3 and the end of the upper handle 1 is 90°, and the angle between the elbow 4 and the end of the lower handle 2 is 90°; there is a smooth transition between the fork head 3 and the end of the upper handle 1, and a smooth transition between the elbow 4 and the end of the lower handle 2.

[0040] In this embodiment, a 90° bend is provided at the distal end of the tweezers, and the shape of the tip portion of the tweezers between the upper handle 1 and the lower handle 2 is different. The tip of the upper handle 1 is a forked fork 3, and the tip of the lower handle 2 is a single root and protrudes into the fork of the upper handle 1 to form a bite relationship.

[0041] The beneficial effects of this embodiment are: the shunt plug can be bent to the required arc with one hand operation, which is convenient for insertion into the coronary cavity; the service life of the coronary shunt plug forceps is extended through the smooth transition between the fork head 3 and the upper handle 1 and the smooth transition between the elbow 4 and the lower handle 2.

[0042] Example 3

[0043] like Figures 1 to 8 As shown, a coronary artery shunt embolization forceps in this embodiment includes all the technical features of Example 2. In addition, the bending shape of the forked head 3 is symmetrically arranged about the longitudinal plane where the elbow 4 is located; the forked head 3 is any one of a semicircular arc, U-shape or V-shape.

[0044] In this embodiment, the tip of the bifurcation head 3 is provided with a smooth curved surface, and the tip of the elbow 4 is also provided with a smooth curved surface, thereby avoiding damage to the shunt plug 7 and the coronary artery incision 8.

[0051] The beneficial effects of this embodiment are as follows: by providing the upper sleeve 5 and the lower sleeve 6, it is convenient to quickly replace the tip structure on the tweezers during use, and at the same time, the manufacturing cost is significantly reduced and the versatility of ordinary tweezers is improved.

[0052] Example 6

[0053] like Fig.12 As shown, a coronary shunt embolization forceps in this embodiment includes all the technical features of Example 5. In addition, a card slot 10 is provided on the upper sleeve 5 and the lower sleeve 6, and a card connection column 9 is provided on the upper handle 1 and the lower handle 2. The card slot 10 of the upper sleeve 5 is card-fitted with the card connection column 9 of the upper handle 1, and the card slot 10 of the lower sleeve 6 is card-fitted with the card connection column 9 of the lower handle 2.

[0054] In this embodiment, the card slot 10 is composed of a strip groove and a circular groove. The strip groove is arranged at the open end of the upper sleeve 5 or the lower sleeve 6, and the spherical groove is arranged on the side away from the open end of the upper sleeve 5 or the lower sleeve 6. When in use, the upper sleeve 5 is inserted into the upper handle 1, and then the circular groove of the card slot 10 is rotated to be connected to the clamping column 9 of the upper handle 1, and the lower sleeve 6 is inserted into the lower handle 2, and then the circular groove of the card slot 10 is rotated to be connected to the clamping column 9 of the lower handle 2.
