Description

Technical Field

[0001] This utility model relates to the field of puncture device technology, specifically to a complete set of puncture devices for pelvic floor reconstruction surgery. Background Technology

[0002] Pelvic floor reconstruction (PFR) is a key technique for treating pelvic organ prolapse (POP) and stress urinary incontinence (SUI). Its core challenge lies in the precise placement of implants (such as mesh or slings) within a narrow, dynamically changing anatomical space. The trocar, as a crucial instrument in the procedure, directly impacts surgical safety, ease of operation, and postoperative outcomes.

[0003] There are many types of trocars on the market. However, the trocars used for pelvic surgery will be different for people with different puncture points, different weights and different pelvises. Therefore, multiple trocars with different curvatures are needed. Traditional trocars have a handle and puncture rod as one unit. However, trocars with different curvatures only have different puncture rods on the handle. Therefore, a complete set of trocars with detachable handle and puncture rod is designed. Utility Model Content

[0004] The purpose of this invention is to provide a complete set of puncture instruments for pelvic floor reconstruction surgery to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a complete set of puncture instruments for pelvic floor reconstruction surgery, including a puncture rod and a handle, wherein the insertion end of the puncture rod is inserted into the connecting end on the handle, and the insertion end is limited within the connecting end by rotating the insertion end or the connecting end, and the connecting end is equipped with a limiting component for restricting the movement of the insertion end.

[0006] Preferably, the handle has a through hole inside, and the insertion end communicates with the through hole after being inserted into the connecting end. The inner diameter of the puncture rod is the same as the inner diameter of the through hole.

[0007] Preferably, the insertion end is symmetrically provided with plug blocks on the outside. The plug blocks are inserted into the slots opened on the connecting end. Rotating the insertion end or the connecting end causes the plug blocks located in the slots to enter the limiting grooves extending outward from the slots.

[0008] Preferably, the limiting component includes a screw sleeve screwed to the connecting end, and a blocking member is rotatably mounted on the screw sleeve. The blocking member is inserted into the slot to prevent the plug block from coming out of the limiting slot.

[0009] Preferably, a screw is screwed onto the handle, and the threaded hole connected to the screw communicates with the through hole. A screwing block is rotatably mounted on the handle, and a positioning element is installed at the end of the screw and inserted into the positioning groove opened on the screwing block. When the screwing block is screwed, the positioning element moves horizontally in the positioning groove, causing the screw to screw into the threaded hole. By adjusting the length of the screw screwed into the through hole, the inner core inserted into the piercing rod is limited.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is assembled into a set, and the same handle can be adapted to puncture rods with different curvatures and lengths. Different puncture instruments can be selected for people with different puncture points, different weights and different pelvises. There is no need to change the entire set of instruments during the operation. It is especially suitable for real-time adjustment in complex cases (such as narrow pelvis or obese patients). It not only reduces the instrument change time, but also saves consumables. By setting a screw at the handle, the inner core inserted into the puncture rod through the through hole in the handle is fixed by the screw, which prevents the inner core from swinging and completes the operation more effectively.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a complete set of puncture instruments for pelvic floor reconstruction surgery, including a puncture rod 1 and a handle 2. The insertion end 3 of the puncture rod 1 is inserted into the connecting end 4 on the handle 2. The insertion end 3 is limited in the connecting end 4 by rotating the insertion end 3 or the connecting end 4. The connecting end 4 is equipped with a limiting component 5 for limiting the movement of the insertion end 3.

[0023] The handle 2 has a through hole 6 inside. After the insertion end 3 is inserted into the connecting end 4, it communicates with the through hole 6. The inner diameter of the piercing rod 1 is the same as the inner diameter of the through hole 6.

[0024] The insertion end 3 is symmetrically provided with a plug-in block 7. The plug-in block 7 is inserted into the slot 8 opened on the connecting end 4. The insertion end 3 or the connecting end 4 is rotated so that the plug-in block 7 located in the slot 8 enters the limiting groove 9 extending outward from the slot 8.

[0025] The dimensions of the limiting groove 9 match the dimensions of the plug block 7.

[0026] The limiting component 5 includes a screw sleeve 51 screwed to the connecting end 4, and a blocking component 52 is rotatably mounted on the screw sleeve 51. The blocking component 52 is inserted into the slot 8 to prevent the plug block 7 from coming out of the limiting slot 9.

[0027] Please see Figure 4 A screw 10 is screwed onto the handle 2. The threaded hole of the screw 10 is connected to the through hole 6. A screwing block 11 is rotatably mounted on the handle 2. A positioning element 12 is installed on the end of the screw 10 and inserted into the positioning groove 13 opened on the screwing block 11. When the screwing block 11 is screwed, the positioning element 12 moves in the positioning groove 13, so that the screw 10 is screwed into the threaded hole. By adjusting the length of the screw 10 screwed into the through hole 6, the inner core inserted into the piercing rod 1 is limited.

[0028] There are various puncture devices in the prior art, distinguished by the different curvatures of the puncture rod on the puncture device. Please refer to [link to relevant documentation]. Figure 1 , Figure 5-7 The document lists some existing puncture rods with different curvatures, without making any improvements or innovations.

[0029] The complete puncture device also includes an inner core and a cleaning brush, both of which are existing technologies. Figure 8 The cleaning brush is part of a complete set of puncture equipment;

[0030] Figure 9 It is the inner core of the complete set of puncture instruments, and the length of the inner core is 15-20cm longer than the longest puncture rod.

[0031] Both the puncture rod 1 and the inner core have graduations on their surfaces, making it easy to know the puncture depth according to the graduations.

[0032] The number of screws 10 on the handle 2 is at least two, which increases the stability of fixing the inner core, avoids the inner core from swinging, and makes the surgery more effective.

[0033] Both the handle 2 and the puncture rod 1 are medical metal consumables that can be disassembled for cleaning and disinfection, which facilitates repeated use and saves a lot of costs.

[0034] Working principle: When the puncture rod 1 is installed on the handle 2, firstly, the limiting component 5 is sleeved on the puncture rod 1, so that the blocking component 52 corresponds to the direction of the insertion end 3. The insertion end 3 is inserted into the connecting end 4, and the insertion end 3 drives the insertion block 7 to be inserted into the slot 8 until the insertion end 3 contacts the bottom of the connecting end 4. Then, the puncture rod 1 or the handle 2 is rotated so that the insertion block 7 rotates into the limiting groove 9. Then, the limiting component 5 is pushed so that the blocking component 52 is inserted into the slot 8. Then, the screw sleeve 51 is screwed onto the connecting end 4. When the blocking component 52 corresponds to the position of the insertion block 7, the insertion block 7 is limited in the limiting groove 9 by the blocking component 52 limiting the rotation of the insertion block 7. At this time, the through hole 6 on the handle 2 is connected to the puncture rod 1, thereby fixing the puncture rod 1 on the handle 2.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
