Abstract

Arthroscopic instrument for high-frequency dissection of tissues of the joints of the extremities, including a handle and a working part in the form of a tube, at the end of which is an electrode with a loop, according to the utility model, contains two manipulators on the handle - proximal and distal, between which the manipulator has a conical module containing an outer tube with a 45-degree beveled tip, in the middle of which there is an inner working tube with a hole inside, which contains an electrode with a cutting loop, and the opposite end of the handle is connected to drain ablation and fluid.

Description

The utility model belongs to medical equipment, namely surgical instruments, and can be used in traumatology for arthroscopic operations on joints.

A surgical instrument for endoscopic operations in gynecology is known, namely a resectoscope.

This tool consists of a handle and a working part. The working part consists of an inner tube with an electrode; external tube with holes for irrigation; tube locks to which the current supply is connected. The handle consists of two branches with a mechanism that drives the inner tube and locks to which the water supply and optical device are attached. With the help of a pedal-switch connected to the console, the current is supplied to the electrodes connected to the locks of the working part of the resectoscope. When the branches of the handle are clamped, the inner tube moves, performing tissue resection with the help of a high-frequency current.

The optical device provides visualization of the operating field. The drainage system ensures fluid circulation in the operational field GrEr/Lumly.roI-tey.sot.tscha/raipvigisiopv/7. paradise

Such a resectoscope has a rather complex design (optical system, irrigation system, obturator, etc.), a limited trajectory of dissection due to the provision of only linear movement of the electrode, and cannot be used as an arthroscopic tool.

A surgical tool for arthroscopic operations, namely a vaporizer, is also known

MARK. This tool consists of a handle at the end with a working part. The handle is connected to the console, and the working part is started using a pedal switch. The working part consists of a tube at the end of which there is an electrode. When a high-frequency current passes through the electrode, a "steam pocket" is created, which causes vaporization of the tissues in it. It is used for radiofrequency vaporization of tissues. The modifications include drainage, which ensures the outflow of liquid and vaporization products from the joint cavity (pNr//rgod.tiek.deriu.eddeziye.pem/IROeTOgMerziye/103097. rat.

This tool performs vaporization, but does not allow tissue dissection; the working part rotates around its axis with the rotation of the operator's hand; the electrode is not variable.

A surgical instrument for arthroscopic operations is also known, namely an arthroscopic retractor. This tool consists of a handle and a working part with blades at the end. At

When the branches of the handle are folded, the blades on the tip are compressed, which is used for mechanical tissue dissection (pnr//teagada. ip.pa/pvigitepiu-aua-aptoz5kKoriui-Koippodo-5idioba-ariuayuga-igutasy-ia-ip5pe.piti|.

Disadvantages of this arthroscopic retractor: mechanical resection is more traumatic for tissues than radiofrequency vaporization; after mechanical tissue dissection, excised tissue circulates in the joint cavity, which impairs visualization and forces the use of additional resources to remove tissue dissection products from the joint cavity.

As the closest analogue, a surgical tool for arthroscopic operations was chosen, namely the Ragadop T2 ApypgouMuapa radio frequency ablator. This tool consists of a handle connected to a console and a working part. The device is activated using a pedal-switch connected to the console. The working part consists of a tube, at the end of which there is a round platform, the lower surface of which contains an annular loop, which, when a high-frequency current passes through it, creates a low-temperature plasma, which performs tissue ablation. It is used for radiofrequency ablation of tissues (nyrz/Lumly.teaisai-demeiortepi.dy/p/Appgoumapa. ran.

Disadvantages of the radio frequency ablator Ragadop T2 AgppgoUmap are the following: the working part rotates around its axis with the rotation of the operator's hand; the tool performs ablation, but does not allow tissue dissection; does not contain a drainage system to remove fluid and remnants of ablation waste from the joint; actuated by a pedal-switch; the electrode is not variable.

The useful model is based on the task of increasing the accuracy of tissue dissection of limb joints, improving visualization during surgery, reducing the level of traumatization of joint tissues, and shortening the time of surgery.

The problem is solved by the fact that the arthroscopic tool for high-frequency ablation of tissues of the joints of the limbs, which includes a handle and a working part in the form of a tube, at the end of which there is a loop, according to a useful model, contains two manipulators on the handle - proximal and distal, between which there is a module launch, behind the distal bo manipulator, a conical module is made, containing an outer tube with a tip beveled at 45 degrees, in the middle of which there is an inner working tube with a hole inside, which contains an electrode containing a cutting loop at the end, and a drain comes from the opposite end of the handle for removal of ablation products and fluid.

The tool can be made both monopolar and bipolar.

The electrode can be made with the possibility of replacement.

The cutting loop-electrode of the arthroscopic tool allows for high-precision dissection of tissues with minimal traumatization. The line of dissection when working with such an electrode is smooth and even, due to which there will be no need for additional processing of tissues. Unlike its analogue, this tool prevents the occurrence of a large number of small tissue dissection products that impair the visualization of the operative field. Microscopic products are removed through drainage, and macro products can be removed with an arthroscopic clip or with a shaver system.

The presence of manipulators for linear movement and rotation around its axis of the working inner tube with an electrode loop makes it easier to work with the tool and shortens the duration of surgical intervention.

The arthroscopic tool allows you to preserve the useful surface properties of individual joint tissues (meniscus, articular lip, etc.) after working with them.

The proposed arthroscopic tool is economically more profitable due to saving time, duration of anesthesia, reducing the need to use other arthroscopic tools (shaver, vaporizer, biter), ensuring comfortable working conditions with the tool for the surgeon.

The essence of the useful model is explained by the drawings, where: in Fig. 1 shows an arthroscopic instrument for high-frequency tissue dissection of limb joints, side view; in Fig. 2 - arthroscopic instrument for high-frequency tissue dissection of limb joints, side view.

The arthroscopic tool for high-frequency tissue dissection of limb joints contains a handle 1 with two manipulators - proximal 2 and distal 3. Between manipulators 2, C is a start-up module 4 with a "start" button 5. Behind the distal Z manipulator is located

Z is a conical module 6 containing an outer tube 7 with a tip beveled at 45 degrees, in the middle of which there is an inner working tube 8. Inside, the inner tube 8 contains a hole in which the electrode 9 is placed, which at the end contains a cutting loop 10. The tool can be made both monopolar and bipolar.

To the other end of the handle 1 of the tool, a drain 11 for the removal of ablation products and fluid, and a power cable 12 are attached.

Electrode 9 with a loop-electrode 10 can be made with the possibility of replacement.

The claimed utility model functions as follows.

The arthroscopic instrument for high-frequency tissue dissection of the joints of the limbs is introduced into the joint with the help of an external 7 tube. After turning the distal C manipulator, the inner working tube 8 is extended, which at the end contains an electrode 9 with a cutting loop 10, to which a high-frequency current is applied. The "start" button 5, located on the start module 4, supplies a high-frequency current to the electrode 9. With the help of the proximal 2 manipulator, the inner working tube 8 is rotated around its axis, which allows you to adjust the plane of the tool. Drainage 11 removes ablation products and fluid from the joint.
