Description

Arthroscope sleeve

Technical Field

The utility model relates to a surgical operation apparatus field, concretely relates to arthroscope sleeve pipe.

Background

Arthroscope is an optical instrument for observing joint inner structure for the endoscope of diagnosing and treating joint diseases, when using surgical instruments, if do not have the protection apparatus of going into the way, cause joint edge soft tissue damage easily when using surgical instruments, what the protection of going into the way of arthroscope operation at present adopted is the sleeve pipe of being made by rigid plastic, this kind of sleeve pipe can cause soft tissue damage and lavage liquid along body external screw thread overflow scheduling problem placing the in-process.

At patent 201810794918.6 a sleeve pipe for arthroscope, adopt flexible material to make, greatly reduced the damage that the sleeve pipe caused for the soft tissue placing the in-process, and soft material combines closely with the soft tissue, the difficult overflow problem that appears, but the sleeve pipe body length that this patent adopted is fixed unchangeable, need choose the sleeve pipe of different specifications for use according to the patient of difference in the operation preparation, it is improper to choose the specification for use, can bring the potential safety hazard for the later stage operation, brought the unnecessary difficulty, how to overcome this problem and become the problem that technical staff in the field need solve.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the above-mentioned weak point of prior art, the utility model provides an arthroscope sleeve pipe, which comprises a pipe body, be equipped with the passageway in the body is inside, the body is radially extensive along at both ends, form inside and outside both sides flange structure, wherein inside flange board is first mounting, outside flange board is the second mounting, near outer tip branch at the body still is equipped with the third mounting, the third mounting is the silica gel nut, wherein the nut passes through the screw thread that sets up and the screw-thread fit that sets up outside the body in the nut, the silica gel nut can be followed the body and reciprocated, adopt the arthroscope sleeve pipe of this kind of structure, provide more stable entry protection passageway for subsequent surgical instruments, can adjust the distance between third mounting and the first mounting according to patient's the condition, thereby adapt to different patient's demands, this sheathed tube commonality has been realized.

The utility model discloses a concrete technical scheme is:

an arthroscope sleeve comprises a pipe body, wherein a channel is arranged in the pipe body, two ends of the pipe body extend outwards along the radial direction of the pipe body to form flange plates on the inner side and the outer side, the inner flange plate is a first fixing piece, the outer flange plate is a second fixing piece, a third fixing piece is further arranged at the position, close to the outer end portion of the pipe body, and is a silica gel nut, the nut is matched with threads arranged outside the pipe body through threads arranged in the nut, and the silica gel nut can move up and down along the pipe body;

by adopting the arrangement, the position of the third fixing piece can be determined according to the specific condition of the joint of the patient, the distance between the third fixing piece and the second fixing piece can be determined according to the thickness and the specific condition of soft tissue at the edge of the joint of the patient, and the specific position of the third fixing piece can be adjusted by rotating the third fixing piece through the matching of the screw thread and the nut, so that the joint of different patients can be adapted, various models are not required to be prepared for use as compared with a sleeve provided in a file, and the universality of the sleeve is improved;

the pipe body and the inner and outer flanges are all made of silica gel materials, so that various problems caused by too high hardness of the existing plastic materials are avoided, and particularly the problem that the plastic materials are easy to leak liquid is avoided;

the sealing pieces which are distributed radially are arranged in the tube body channel, and the center of each sealing piece is provided with a cut, so that the passing in and out of arthroscopic instruments can be ensured, and the lavage fluid can be effectively prevented from overflowing in a large amount;

before an operation, an operation clamp is used for clamping the inner flange plate, the inner flange plate is plugged into a soft tissue cut, the first fixing piece, namely the inner flange plate is tightly attached to the inner layer of the cut, the third fixing piece, namely the silica gel nut is rotated to enable the third fixing piece to be tightly attached to the outer layer of the cut, and the joint cut soft tissue and the sleeve are fixed with each other; when in operation, the surgical instrument enters the soft tissue through the channel in the tube body to operate; after the operation, the surgical instrument and the arthroscope sleeve are taken out.

In conclusion, by adopting the arthroscopic cannula with the structure, the first fixing piece, namely the inner flange plate is tightly attached to the inner layer of the incision, and the third fixing piece is rotated to be tightly attached to the outer layer of the incision, so that the soft tissue of the joint incision and the cannula are fixed with each other, the arthroscopic cannula can be suitable for arthroscopic surgeries of different patients, and the universal performance of the cannula is realized; the arthroscope sleeve with the structure provides a more stable access protection channel for subsequent surgical instruments.
