Description

Surgical instrument with reusable handle

Technical Field

The utility model relates to a medical apparatus.

Background

In the operation, the situation that the operation treatment of human tissues needs to be carried out by functional ends such as forceps, vertebrae, forceps, nucleus pulposus forceps and the like often occurs, and the existing handle and the functional ends are integrated, so that a complex disinfection procedure is needed after the operation, the risk of incomplete disinfection exists, or the whole body is used as a disposable instrument, and the cost is high.

For example, in spinal surgery, it is often the case that a laminectomy rongeur is required to bite dead bone or to trim bone stumps. The handle and the forceps mouth of the existing vertebral plate rongeur are integrated, so that either a complicated disinfection procedure is required after the vertebral plate rongeur is used and the risk of incomplete disinfection exists, or the vertebral plate rongeur is used as a disposable instrument. And the angle of the forceps mouth relative to the handle is fixed, so that the operation at a special angle is inconvenient. If the integrated vertebral plate rongeur is repeatedly used, the structure of the forceps mouth and the linkage rod is complex and compact, so that the thorough disinfection is difficult, and nosocomial infection is easily caused; if the whole body is used once, the cost is high, resources are wasted, and burden is brought to the environment; the angle of the clamp mouth relative to the handle is fixed, and the operation is inconvenient at a special angle.

As shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, fig. 7, fig. 8, fig. 9, fig. 10:

in an embodiment of the present invention, a pair of lamina rongeurs having reusable handles is provided.

The fixed handle 1 is connected with the rotating handle 2 through a pin 12 in the middle, the spring 3 is sleeved on the linkage rod 5, and two ends of the spring 3 respectively abut against the step of the linkage rod 5 and the end surface of the stainless steel pipe part of the lower clamp mouth 7. The linkage rod 5 penetrates through a stainless steel pipe on the lower clamp mouth 7 and then is connected with a thread 6C on the upper clamp mouth 6 through a thread at the front end part, the upper clamp mouth 6 is matched with a guide groove 7C on the lower clamp mouth 7 through a guide groove 6A, the upper clamp mouth 6 is matched with a flat chute 7D on the lower clamp mouth 7 through a flat chute 6B, one end of the stainless steel pipe part of the lower clamp mouth 7 is provided with a thread 7A, the lower clamp mouth 7 is also provided with a plurality of stop planes 7B, and the lower clamp mouth 7 is connected with a thread 1A of the fixed handle 1 through a thread 7A. The stop screw 4 is installed on the fixed handle 1 after penetrating through a screw hole 1B formed on the fixed handle 1 in a threaded fit manner, and the end face of the stop screw 4 abuts against a stop plane 7B of a stainless steel pipe part on the lower clamp mouth 7.

As shown in fig. 3:

the fixed handle 1 and the rotating handle 2 made of stainless steel or polymer composite material can be independently assembled into a handle assembly 100.

The stainless steel spring 3, the linkage rod 5, the upper plier mouth 6 and the lower plier mouth 7 can be independently assembled into a plier mouth assembly 200, and then the plier mouth assembly 200 and the handle assembly 100 are assembled together through the threads 1A on the fixed handle 1 and the threads 7A on the lower plier mouth 7.

As shown in fig. 4:

after the forceps mouth assembly 200 and the handle assembly 100 are assembled in place, the plane 7B arranged on the lower forceps mouth 7 is positioned below the stop screw 4, the stop screw 4 is screwed, and the forceps mouth assembly can be fixed in the circumferential direction by abutting against the plane 7B arranged on the lower forceps mouth 7, so that the rotation of the forceps mouth assembly is prevented.

As shown in fig. 5:

when the pliers mouth assembly needs to rotate for a certain angle, the stop screw 4 can be loosened, the pliers mouth assembly is rotated, and when the pliers mouth assembly rotates to the required angle, the stop screw 4 is screwed again to fix the pliers mouth assembly.

As shown in fig. 6:

one end of the spring 3 props against the step surface of the linkage rod 5 to push the linkage rod 5 leftwards, so that the clamp mouth is in an open state; the other end of the step surface of the linkage rod 5, namely the rear end part of the linkage rod 5 is propped against the arc surface of the rotating handle 2 to push the rotating handle 2 leftwards, so that the handle 2 is in an open state.

As shown in fig. 7, 8, 9, and 10:

the bottom of the upper tong mouth 6 is provided with a guide groove 6A, the top of the lower tong mouth 7 is provided with a guide groove 7C, and the guide groove play a role in guiding the running direction of the upper tong mouth 6 through a groove structure; go up tong mouth 6 both sides and respectively have a draw-in groove structure 6B, lower tong mouth 7 both sides respectively have a parallel spout structure 7D, and the two is spacing to the operation of going up tong mouth 6 through parallel spout structure for go up tong mouth 6 and lower tong mouth 7 can only parallel slide, and can not separate from top to bottom.

The upper tong mouth 6 is connected with the linkage rod 5 through a thread 6C of the upper tong mouth 6; the linkage rod 5 drives the upper tong mouth 6 to move in parallel relative to the lower tong mouth 7 until the upper tong mouth 6D is closed, and reliable biting force is provided when the upper tong mouth 6D and the lower tong mouth 7E are occluded.

When the clamp is used, the rotating handle 2 is pressed by a hand, the arc surface of the rotating handle 2 is abutted against the step surface of the linkage rod 5 to move rightwards, and the spring 3 is compressed, so that the upper clamp mouth 6D and the lower clamp mouth 7E are occluded. When the rotary handle 2 is released and pressed, the linkage rod 5 drives the handle and the forceps mouth to return to the opening state again under the action of the elastic force of the spring 3.

After the combined pliers is used, the stop screw 4 can be conveniently unscrewed, the thread 1A on the fixed handle 1 and the thread 7A on the lower pliers mouth 7 are unscrewed, the pliers mouth combined body 200 is detached, the handle combined body 100 is reserved, and the pliers mouth combined body 200 is replaced by a new pliers mouth combined body 200.

The handle assembly and the plier nozzle assembly can be conveniently separated and reassembled; the clamp mouth assembly can rotate circumferentially relative to the handle to adjust the angle of the clamp mouth. After the vertebral plate rongeur is used, the forceps mouth assembly can be conveniently detached, the handle assembly is reserved, and a new forceps mouth assembly is replaced; at some inconvenient positions, can rotate the pincers mouth, adjust pincers mouth angle, make the simple operation. Therefore, the mouth part and the handle part of the vertebral plate rongeur are completely in non-contact, so that the risk of nosocomial infection caused by incomplete disinfection is avoided, the handle is reserved, only the forceps mouth combination body is used at one time, the cost is reduced, the burden on resources and environment is reduced, the angle of the forceps mouth can be adjusted, and the operation is convenient and fast.

In this embodiment, the functional ends are the upper jaw opening 6D and the lower jaw opening 7E, and in other embodiments, the jaw assembly 200 may be a functional assembly, and the functional ends may be a vertebral body, or forceps, or a nucleus pulposus clamp.
