All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the present utility model, an embodiment of an ultrasound assembly apparatus for arthroscope is provided, comprising a scope sheath 1, an endoscope 2 and a scope. In this and other embodiments that follow, the end that is closer to the human body is referred to as the head and the opposite end is referred to as the tail, as exemplified by fig. 1, 3 and 4, where the tip of the penetration sleeve 12 is the head.

Wherein the sheath 1 plays the role of piercing and holding, as shown in fig. 1, 3 and 4, the sheath 1 is divided into a piercing sleeve 12 and a connecting seat 11, wherein the piercing sleeve 12 is used for conveniently penetrating into a human body, generally a hard material, a tip is arranged, the endoscope 2 extends out from the tip of the piercing sleeve 12 to visit the interior of the human body, the connecting seat 11 is used for stabilizing the endoscope 2, and a bulge-shaped structure or other structures with similar functions are generally arranged at the tail part of the endoscope 2, so that the endoscope 2 can be abutted on the connecting seat 11, on one hand, the deep depth of the endoscope 2 can be limited, and on the other hand, the shaking generated by the dead weight of the endoscope 2 can be reduced by abutting the tail part of the endoscope 2.

After the endoscope sheath 1 penetrates into a human body, the endoscope 2 is required to penetrate into the human body from the inside of the endoscope sheath 1 to observe the internal structure of the human body, in the prior art, the endoscope is generally composed of a lens with a specific inclination and a cable for transmitting the observation data of the lens, when other angles are required to be observed, the endoscope 2 is generally extracted to reinsert a new endoscope 2 with a corresponding angle, or the endoscope is reinserted from other positions, and the two modes can cause damage to the human body, are not beneficial to recovery, and increase the infection risk. In this embodiment, the head of the endoscope 2 is provided with a flexible portion 21 that can rotate and bend, and an ultrasonic probe 22 that can expand the observation field is installed on the head of the flexible portion 21, and the flexible portion 21 can flexibly move in a certain range in the human body with the ultrasonic probe 22, so that the field of view observed once is larger, the problem of multiple penetrating instruments is avoided, and meanwhile, the observation requirement is met as much as possible by one penetrating. That is, in the embodiment of the present utility model, only one endoscope 2 is needed to meet most observation requirements, and there is no need to prepare a plurality of endoscopes 2 with different angles as in the prior art, so that the cost is greatly reduced, and in the embodiment of the present utility model, the arthroscope or the endoscope 2 can be manufactured into a disposable device, and the need to repeatedly disinfect the arthroscope as in the prior art is avoided, so that the cost is saved due to the requirement of secondary use, and the risk of cross infection is further reduced.

The present embodiment also has a viewing device for displaying images viewed by the endoscope 2, which in general embodiments is typically located outside the arthroscope, including a cabinet for processing graphics signals and a display for displaying images, and in some embodiments has a pulley for easy movement.

The structure of the ultrasound probe 22 is varied, and in one preferred embodiment, see fig. 1 and 3, the structure of the ultrasound probe 22 is similar to an umbrella rib or claw, the flared end of each branch is referred to as the flared end, the common location of all branches is referred to as the common end, and the ultrasound probe 22 can be flared when the front end of the endoscope 2 is extended such that the ultrasound probe 22 extends out of the penetration sleeve 12. And each open end of the ultrasonic probe 22 is provided with an ultrasonic probe, after the image collected by each ultrasonic probe is transmitted back to the observation device, the observation device synthesizes the image into a complete image, thereby expanding the field of view, and when the ultrasonic probe needs to be retracted, the umbrella-shaped ultrasonic probe 22 can be retracted by means of the opening edge of the puncture sleeve 12 only by pulling the endoscope 2 back. The flexible part 21 in the embodiment can make the ultrasonic probe 22 perform some turning actions by means of human body structure, and can peep deeper or at a position which is harder to reach in angle without secondary puncture, thereby reducing the injury of patients.

In some further improved embodiments, a remote control handle 23 is also provided, the remote control handle 23 being mainly used for controlling the degree of opening of the ultrasound probe 22, in this embodiment by controlling the contraction of the cable to open the ultrasound probe 22. Specific control methods the present utility model provides two examples to illustrate separately.

One of them can be seen in fig. 1 and 2, in this embodiment, the remote control handle 23 is in the shape of a rotating body, wherein the remote control handle 23 and the connection seat 11 have a conical surface, and when the remote control handle 23 is rotated, the cable is wound on the conical surface, so that the length of the cable is shortened, and the other end of the cable is bifurcated and connected to each open end of the ultrasonic probe 22, so that when the length of the cable is shortened, the ultrasonic probe 22 can be pulled back, and the ultrasonic probe 22 is opened.

Another embodiment can be seen in fig. 3, the other parts of the embodiment shown in fig. 3 being identical to fig. 1, with only the remote control handle 23 being partially different. In the embodiment shown in fig. 3, one of the two grips of the remote control handle 23 is fixed to the endoscope 2, and the other is hinged to the endoscope 2, while the end extending into the endoscope 2 is connected to a cable. Thus, when held by a worker, the movable grip pulls the cable rearward, and finally the other end of the cable is bifurcated into each of the flared ends, thereby allowing the ultrasound probe 22 to be flared.

In both embodiments, when it is desired to retrieve the ultrasound probe 22, the cable may be loosened by reverse operation, and the endoscope 2 may be withdrawn, and the ultrasound probe 22 may be retracted by the opening edge of the puncture sleeve 12.

In some further improvements, in order to collect more data at one time, a second probe 24 is further provided, and in this embodiment, the second probe 24 is mounted at an umbrella-shaped common end of the ultrasonic probe 22, so that the front of the second probe 24 is not shielded, and the accuracy of the result of the second probe 24 is increased.

In another type of embodiment of the ultrasonic probe 22, as can be seen in fig. 4, the ultrasonic probe 22 is bulb-shaped, the flexible portion 21 is a metal hose, the emitting and receiving capabilities of the bulb-shaped ultrasonic assembly are both better than those of the existing lens, and meanwhile, the flexible portion 21 is a metal hose, so that the flexible portion 21 can be deformed by external force, but can be kept in a deformed state when not subjected to external force, thus the ultrasonic probe 22 can be shaped by means of the internal structure of a human body during diagnosis and treatment, so that the ultrasonic probe 22 can extend into a more complex human body structure, and a position which is difficult to observe in the prior art is observed.

In some further modifications, the endoscope 2 is divided into a housing 25 and an inner wire 26 for convenience in controlling the extension length of the ultrasonic probe 22.

The shell 25 is of a hard structure, conveniently penetrates into the puncture sleeve 12, is hollow and is specifically divided into a sleeve shell 253 and an abutting shell 252 which are communicated with each other, the sleeve shell 253 stretches into the shell 25 for the telescopic use of the inner wire 26, the abutting shell 252 provides a space for controlling the inner wire 26 by the adjusting handle 27, and the abutting shell 252 is generally abutted to the connecting seat 11 so as to stabilize the inner wire 26 and prevent the endoscope 2 from being mixed or excessively stretched into the connecting seat to be difficult to pull out.

The inner wire 26 mainly plays a role in transmitting observation signals, and meanwhile, the ultrasonic probe 22 with certain hardness can push the head of the inner wire 26.

As shown in fig. 4, 5 and 6, the inner cavity of the abutting case 252 is for providing a movable space for the sliding block 271, while the abutting case 252 may serve as a member abutting against the connection base 11, and the inner cavity of the sleeve case 253 is for accommodating the inner wire 26. The sliding block 271 is sleeved outside the inner wire 26 and fixedly connected to the inner wire, and when the sliding block 271 is shifted, the inner wire 26 is driven by the sliding block 271 to move together, so that the movement of the inner wire 26 can be controlled.

In some further improvements, for more convenient control of the movement of the inner wire 26, an adjusting handle 27 is further provided, where the adjusting handle 27 has two sections, one section is fixed on the abutting shell 252, and the other section is hinged on the abutting shell 252 and one end extending into the abutting shell 252 is connected to the sliding block 271, so that when an operator adjusts the distance between the two sections of the adjusting handle 27, one end extending into the abutting shell 252 drives the sliding block 271 to move, and the inner wire 26 extends forward, and the ultrasonic probe 22 at the head of the inner wire 26 also extends forward.

For ease of use by the operator, so that the inner wire 26 can be reset without controlling the adjustment knob 27. In some preferred embodiments, the adjustment handle 27 also includes a return spring 251.

Specifically, the return spring 251 is disposed between the inner wire 26 and the inner wall of the abutting shell 252, and two ends of the return spring 251 are connected to the inner cavity wall of the abutting shell 252, which is close to the connecting seat 11, and the sliding block 271, so that when the adjusting handle is not controlled, the return spring 251 can push the sliding block 271 to reset, and control is facilitated. The sliding block 271 is controlled by the adjusting handle 27, and there are various control methods, for example, a middle section of the adjusting handle is hinged to the abutting shell 252, and an end of the movable end is hinged to the sliding block 271; the end of the adjusting handle is provided with a sliding block, the sliding block 271 is provided with a sliding groove and the like, so that the adjusting handle 27 can drive the sliding block 271 to slide, in the embodiment, a gear is arranged at one end of the adjusting handle close to the sliding block 271, a channel is cut out on the surface of the sliding block 271, and a rack is arranged in the channel, so that when an operator kneads the adjusting handle 27, the gear at one end of the adjusting handle 27 drives the rack to move, and then drives the sliding block 271 to move.

In order to be able to detect more data with one detection, in some more preferred embodiments the outer wall of the flexible portion 21 is also provided with a second probe 24 for a larger range of observations.

In the general embodiment, the specific structure of the sheath 1 is that a puncture sleeve 12 and a connecting seat 11 can complete puncture and exploration, but the operation feel is poor in this way, and the force is difficult to generate in the use process and deflection is easy to occur.

In order to facilitate holding and puncturing, in some preferred embodiments, a connecting portion 13 is further sleeved outside the puncturing sleeve 12, the connecting portion 13 is fixedly connected to the connecting seat 11, operating handles 14 are symmetrically arranged on two sides of the connecting portion 13, and the operating handles 14 can be held during puncturing to avoid the puncturing sleeve 12 from rotating to damage the human body.

In other embodiments, the operation handles 14 are all provided with the communication valves 141, and the operation handles 14 are hollow, so that liquid can be injected into the cavities of the operation handles 14 or the light source can assist in probing, and damage to human bodies is avoided.
