DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 1-2 , which is the first embodiment of the present utility model, provides a proximal anastomosis auxiliary device, including an induction mechanism 100, the induction mechanism 100 includes a placement box 101, the inner cavity of the placement box 101 is cooperated with a puncture needle 103, the bottom of the puncture needle 103 is movably sleeved with an alignment sleeve 104, the bottom of the alignment sleeve 104 is fixedly connected to a guide plate 105, the guide plate 105 is cooperated with a fitting mechanism 200, the fitting mechanism 200 includes a double sliding track 203 slidably connected to the lower surface of the guide plate 105, the inner side surface of the double sliding track 203 is cooperated with an alignment mechanism 300, the alignment mechanism 300 includes an outer abutment plate 301 that is clamped to the inner wall surface of the guide plate 105, and the side surface of the outer abutment plate 301 is fixedly connected to the first ear plate seat 302.

[0028] Specifically, the cooperation between the summarizing mechanism 100 and the fitting mechanism 200 and the alignment mechanism 300 can provide auxiliary support for different patient positions during surgery, and the effect of surgical treatment is better. The cooperation between the placement box 101 and the puncture needle 103 can stably store the puncture needle 103, which is convenient for the next surgery. The fixed cooperation between the alignment sleeve 104, the guide plate 105 and the puncture needle 103 allows the puncture needle 103 to move for puncture, which can meet the surgical needs of different patient positions and significantly improve the surgical efficiency. The clamping connection between the outer abutment plate 301 and the guide plate 105 allows the puncture needle 103 to remain in a fixed position, meeting the needs of fixed-point surgery. The fixed connection between the first ear plate seat 302 and the outer abutment plate 301 further clamps the guide plate 105.

[0029] Furthermore, the inner side surface of the first ear plate seat 302 is rotatably sleeved with a long shaft rod 304, the end surface of the long shaft rod 304 is rotatably connected to the second ear plate seat 303, and the side surface of the second ear plate seat 303 is fixedly connected with a sliding column sleeve 305, and the first ear plate seat 302, the second ear plate seat 303 and the long shaft rod 304 are each provided with two groups, and the two groups of first ear plate seats 302, the second ear plate seat 303 and the long shaft rod 304 are distributed in a ring on the side of the double sliding track 203.

[0030] Preferably, the rotational cooperation between the first ear plate seat 302, the long shaft rod 304 and the second ear plate seat 303 allows the outer abutment plate 301 to be limited in position and not move. When a long operation is required at a certain position, this method can better provide auxiliary effects. The fixed connection between the second ear plate seat 303 and the sliding column sleeve 305 allows the second ear plate seat 303 to move up and down, which facilitates the stable abutment of the outer abutment plate 301 and also allows the puncture needle 103 to move flexibly and remain stationary.

[0031] It should be noted that the double sliding track 203 is an integrally formed double concentric circle track, and a plurality of lightweight springs 204 are fixedly connected between the concentric circles.

[0032] Afterwards, the one-piece molding setting of the double sliding track 203 allows the inner and outer sides of the double sliding track 203 to be stably supported when sliding with the guide plate 105, while also ensuring the puncture of the puncture needle 103, providing good auxiliary effects for subsequent surgical equipment.

[0033] Example 2

[0034] Reference Figure 2-3 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving the continuous abutment effect of the outer abutment plate 301.

[0035] Specifically, the center of the sliding sleeve 305 is threadedly connected to a screw rod 306 , the screw rod 306 is fixedly connected to the backing plate 201 via a bearing at the bottom, and a knob 307 is inserted into the end surface of the screw rod 306 .

[0036] Furthermore, the threaded connection between the screw rod 306 and the sliding sleeve 305 allows the sliding sleeve 305 to be adjusted up and down, and the guide plate 105 is limited and locked when sliding, which facilitates the fixed-point puncture of the puncture needle 103 and also meets the subsequent surgical requirements.

[0037] Preferably, the fitting mechanism 200 includes a guide block 202 , and the guide block 202 and the double sliding rails 203 are fixedly connected to the upper surface of the pad 201 .

[0038] Among them, the fixed arrangement of the guide block 202 and the double sliding track 203 allows medical personnel to quickly locate the position of the device, indirectly improving the operation efficiency and shortening the operation time.

[0039] Example 3

[0040] Reference Figure 2-5 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving stable limiting and creating surgical area effects.

[0041] Specifically, the maximum rotation angle of the long shaft rod 304 is an acute angle, and the second ear plate seat 303 is arranged at a higher height than the first ear plate seat 302 .

[0042] Furthermore, the acute angle setting of the long shaft rod 304 prevents the long shaft rod 304 from being overly strained during rotation, thereby extending the service life of the long shaft rod 304 and indirectly ensuring the flexible puncture function of the puncture needle 103. The second ear plate seat 303 is set higher than the first ear plate seat 302, which allows the rotational motion to be transmitted without the problem of rotation jamming.

[0043] Preferably, a locking ring 102 is fixedly connected to the upper surface of the placement box 101 , the inner side of the locking ring 102 is engaged with the puncture needle 103 , and the side of the guide plate 105 is connected to a blood drainage bag 106 .

[0044] Among them, the locking ring 102 is fixed on the upper surface of the placement box 101, so that the puncture needle 103 can be stably stored. At the same time, the connection between the guide plate 105 and the blood drainage bag 106 can form a blood-free environment in the area contacted by the puncture needle 103, facilitating the subsequent operation.

[0045] Working principle: First, take out the puncture needle 103 from the placement box 101, and then fix it on the upper surface of the guide plate 105 through the alignment sleeve 104, and then connect the blood drainage bag 106 with the guide plate 105; before the operation, let the guide plate 105 slide and connect with the double sliding track 203, and the light spring 204 is fixed inside the double sliding track 203, so that the puncture needle 103 can achieve the puncture and blood drainage effect in different patient areas, creating a bloodless operation area. When performing targeted surgery on certain areas, the pad 201 is installed with the screw 306, and then the screw 306 and the knob 307 are plugged and installed. When the knob 307 is turned, the sliding sleeve 305 is threadedly displaced on the surface of the screw 306, further driving the second ear plate seat 303, the long axis rod 304 and the first ear plate seat 302 to rise and fall and articulate. During this process, the outer abutment plate 301 abuts and fixes the guide plate 105, completing the targeted puncture of the patient area, which facilitates the normal progress of subsequent operations.
