A laparoscopic suturing device is provided. The suturing device can pass a suturing needle back and forth between jaws of a jaw assembly to suture tissue at a surgical site in a minimally invasive procedure. The jaw assembly can have a pivotable jaw member in each jaw to position the jaw assembly and needle in a low-profile stowed configuration for insertion through a low diameter surgical port. The jaw assembly can be actuated by a handle assembly that provides simultaneous needle passing from a driving jaw to a receiving jaw and latching the needle within the receiving jaw in a single trigger cycle.20 24 22 73 26 15 O ct 2 02 4 A B S T R A C T O F T H E D I S C L O S U R E 2 0 2 4 2 2 7 3 2 6 1 5 O c t 2 0 2 4

The invention discloses a retractor fixing system for a surgical operation, and belongs to the technical field of medical instruments. In order to overcome the technical defects that an existing manual retractor needs full-time personnel to apply force continuously, and a mechanical retractor is insufficient in degree of freedom of adjustment (limited by plane adjustment of + / -15 degrees) and cannot adapt to instruments of multiple specifications, a modular solution is provided. Quick assembly and disassembly within 5 seconds are achieved, and the clamping force is larger than or equal to 500 N; the multi-direction adjusting module adopts a dual-mode universal damping ball head assembly (6) and supports a first connection mode and a second connection mode (parallel traction force distribution), and a hexagonal damping adjuster (601) can accurately control the traction force; according to the instrument adaptation module, a retractor adapter (7) is provided with an ISO 13485 standard interface (701) and an anti-disengagement clamping groove (702) and is compatible with retractors and tissue forceps with different diameters, a chamfer design (R is larger than or equal to 1 mm) supports a medical disinfection bag to wrap the system in a sterile mode, the surgical field exposure stability is remarkably improved (the tremor amplitude is reduced to be smaller than or equal to 0.1 mm), and the instrument adaptation module is suitable for complex anatomical structure adjustment of open surgery. The attached drawings of the abstract show the system assembly structure and the profile characteristics of the universal ball head assembly.

This invention discloses a reusable, quick-release tissue forceps, comprising two handles, a locking component at the junction of the two handles, an mounting sleeve connected to one side of each handle, a slot formed in the top inner part of the mounting sleeve, a first fixing component corresponding to the slot, an annular groove formed on the inner side of the mounting sleeve, a second fixing component corresponding to the annular groove, the second fixing component comprising a circular block, a moving rod formed inside the circular block, grooves formed on both sides of the moving rod, balls corresponding to the grooves, circular grooves formed on both sides of the circular block, the balls corresponding to the grooves, the annular grooves corresponding to the balls, a moving component on one side of the circular block, a forceps head connected to one side of the circular block, and a moving block comprising a moving component. This invention conveniently and efficiently achieves quick disassembly and stable function.

The orthopedic reduction forceps comprise two single-blade forceps fixed by a fixing bolt, each single-blade forceps is composed of a forceps head, a forceps body and a forceps handle from head to tail, the thickness of the forceps head of each single single-blade forceps is larger than 4 mm, the thickness of a cutting edge of each single single-blade forceps is larger than 1 mm, a clamping opening of each forceps head is provided with a plurality of reduction teeth, and the top end of each forceps head is further provided with tip teeth; according to the invention, the tip teeth can be easily inserted between fracture blocks, tightly attached to the fracture blocks and stably grasp the fracture blocks, the fracture broken ends can be fixed by matching with the reduction teeth, the fracture broken ends can be kept in a good alignment relationship, and meanwhile, some small tubular bones can be clamped; the forceps body is widened and thickened, the forceps body is short and thick, the fracture broken end can be better held, inconvenience caused by narrow operation space is reduced, and the situation that the fracture broken end cannot be stably held due to the fact that bent forceps and tissue forceps are too long and too thin, and effective reduction is difficult occurs.

The utility model provides a kind of auxiliary lifting device for operation and the operating bed with it, wherein auxiliary lifting device includes L-type rod, adjusting rod, first adjusting structure, first clamping piece and tissue forceps;L-type rod is suitable for being installed on bed;Adjusting rod is installed on L-type rod;First adjusting structure is installed on adjusting rod;First clamping piece is installed on first adjusting structure;Tissue forceps are installed on first clamping piece.Use, L-type rod is installed on bed, tissue forceps are clamped and fixed, the angle of adjusting rod, first adjusting structure and first clamping piece is adjusted in turn, so that tissue forceps reach optimal operation position;After adjustment is completed, use tissue forceps to hold and pull focus tissue, and doctor carries out focus tissue resection.In the utility model, auxiliary lifting device can be flexibly adjusted angle, so that tissue forceps reach optimal position;In addition, tissue forceps can be firmly fixed, to prevent tissue forceps displacement or shaking during lifting and traction, so that clear operation visual field is maintained all the time.

The tissue forceps comprise two forceps beaks, a main joint part and a sub-joint part, each forceps beak is provided with an occlusion assembly, a side opening is formed in one side of each forceps beak, the occlusion assemblies are arranged on the side openings, each occlusion assembly comprises a clamping plate, the clamping plates are located in the side openings, and the main joint part and the sub-joint part are arranged on the main joint part. A plurality of meshing teeth are evenly and fixedly connected to the sides, away from the forceps beak, of the clamping plates, a through opening is formed in the inner side of the main joint part, the two sides of the through opening are each of an opening structure, the sub-joint part is inserted into the through opening, and a shaft column is horizontally and fixedly connected to the middle of the through opening and rotationally connected to the middle of the sub-joint part in a sleeving mode. According to the utility model, the occlusion component carrying the occlusion teeth is arranged on the forceps beak and can be replaced, on one hand, the occlusion components with different tooth shapes can be replaced according to different clamped tissues, and on the other hand, when the occlusion teeth are abraded, the occlusion components can be directly replaced, the whole forceps body does not need to be scrapped, and waste is avoided.
