Description

The invention relates to medical equipment, namely to the instruments used in neurosurgery. Instead of extensive trepanning of the skull, and at the same time obtaining disability, minimally invasive intervention allows you to avoid all this by applying new medical technologies when performing surgical interventions using endosurgical equipment and tools.

From the current level of technology known simulator ventriculoscopy, comprising a housing connected to the housing simulator tube made in the form of a hollow cylinder with magnets inside and represents the anchor of the linear electromagnetic motor of the force generating mechanism, located on the body cranes aspiration and irrigation, position sensors associated with these cranes and installed with the possibility of transmitting signals about their position in the control unit to regulate the flow of liquids in the virtual space when simulating In a surgical operation, a linear electromagnetic motor installed in the housing of the ventriculoscopy simulator with an anchor containing a grip of the endoscopic instrument simulator, while the ventriculo scopic simulator is installed in the force generating mechanism to simulate manipulations and then stationary fixation and placement of the endoscopic instrument in the gripper of the linear electromagnetic motor which has the ability to offset the signal of the control unit, (see as №RU 181387, IPC G09B 23/28, publ. 07.11.2018)

The disadvantages of this technical solution are that it is a simulator, which is used only for educational purposes.

A device for atraumatic access to the cavity of intracerebral hematomas and formations of deep localization is known, including a tube made of a transparent material with an outer diameter of 11 mm and a length of 130 mm, a trocar 270 mm long with a cone-shaped end and a universal stopper made with the possibility of free movement around the tube and made in the form of a cylinder having a side and platforms for attachment to the bone, as well as a restrictive screw, made with the possibility of fixation on the tube, (see patent No. RU 179640, IPC AV 17/00, o May 21, 2018).

The disadvantage of this device is the lack of use in complex operations where you need to connect more tools to penetrate into the operated area.

A device for installing medical instruments is known, comprising a housing with an instrumental guide, a means of prefixing a medical instrument, a trigger mechanism with a depth scale printed on the housing, and means for feeding a medical instrument in the form of telescopic tubes placed inside the housing, the first of which is fixedly connected to the housing and the second made movable, spring-loaded, installed end in the end of the guide housing and has a stopper for holding the medical instrument and installed in the slot of the body with the possibility of longitudinal movement and interaction with the end of the slot, and the trigger mechanism is located on the body with the ability to move, fix and interact with the stop to set the depth of installation of medical instruments, characterized in that the minimum portion of the movable tube located in the fixed tube , is not less than half the outer diameter of the movable tube, and the distance between the end guide of the housing and the fixed tube end facing it It leaves from 2 to 25 outer diameters of the movable tube, wherein the means for pre-fixing a medical instrument and a detent for retaining the medical instrument adapted to cooperate with the medical instrument inserted from one and / or from the other end of the housing (see. patent №RU 2238043, IPC А61В 17/00, А61В 17/34, publ. 10/20/2004).

The disadvantages of this device are that its use is limited, as it is used only in the epidural or subdural space of the spinal cord.

Closest to the claimed technical solution for the combination of essential features is a device for endoscopic removal of hypertensive intracerebral hematomas, containing a port made in the form of a tube with a working channel with a diameter of 10 mm, one end of which is provided with a washer and a platform for fixation, and on the other end there are four holes with a diameter of 1 mm for emptying the liquid part of the hematoma after its puncture, notches with a pitch of 10 mm are applied on the outer surface of the port (see patent No. RU 1600304, IPC А61М 1/00, publ. 10.03.2016).

A disadvantage of the known device is that it has only one working channel, which significantly reduces its capabilities.

The task, the solution, which directed the claimed technical solution, is to expand the functionality of the device for endoscopic intervention.

The problem is solved in that the device for endoscopic intervention, made in the form of a tube with a working channel, and the tube contains 4 channels of different diameters, one of which is provided with a lock for fixing the optics, the working end of the tube is equipped with a rounded head.

Distinctive signs, namely, that the proposed device is congruent with the existing optical tubes from different manufacturers. It is a thin metal tube with an obturator, the distal end of which is rounded, which facilitates the passage of the tube through the brain tissue and allows you to "push apart" the tissue, thereby reducing the possibility of damage to the vessels, as well as pathways. At the proximal end of the lock, which is necessary for tight fixation of the optical tube, which is installed after removing the obturator. There are 3 additional channels on the barrel of the tube: one straight working channel for inserting instruments and two side channels with cranes for introducing and draining fluid, or one of these channels can also be used for inserting flexible instruments of small diameter. Thus, the tube design allows the use of a bimanual technique and at the same time use an additional channel for irrigation. Due to the small diameter of the tube and the rounded distal end of the obturator, when inserted into the brain, it is possible to move the blood vessels and pathways apart, which minimizes the risk of hemorrhage, as well as focal neurological symptoms. The proposed tube with four integrated channels, while fulfilling all requirements when working with it, makes it possible to minimize the possibility of obtaining postoperative complications, during operations, due to the precise introduction of instruments to the surgical target. Also provide a maximum overview of the endoscope during surgical intervention on intraventricular structures, reduce the operation time and increase the reliability of the latter by introducing an “additional” instrument (bimanual technique). The minimum of injury and a good cosmetic effect is also achieved due to the small incision and small diameter of the trephination hole with a diameter of 6.5-7.5 mm for insertion of the tube. At the same time, the wound healing time and the postoperative rehabilitation period is shortened several times. To date, many interventions are reviewed in the direction of endoscopic technology. In addition, this device will be most effective when carrying out endoscopic operations in children when using it in pediatric neurosurgery for the pathology of the cerebrospinal fluid system.

The analysis of the known technical solutions carried out according to the scientific, technical and patent documentation showed that the set of essential features of the proposed technical solution is not known from the prior art, therefore, it meets the conditions of patentability "novelty."

The claimed technical solution is illustrated by the drawings:

FIG. 1 - a device for endoscopic intervention, a general view in section;

FIG. 2 - device for eschuscopic intervention "top view.

A device for endoscopic intervention, contains a tube 1, the working end - the head 2, which has a rounded shape. The rounded shape of the head 2 is designed to facilitate the passage of the tube 1 through the brain tissue and reduce the possibility of damage to the blood vessels. Tube 1, is used to introduce neurosurgical instruments in the operated field and goes into the housing 3, designed for branching instrumental channels for comfortable operation of the operating surgeon. In the tube there are four channels 5 and 6, one of which, channel 5, is fitted with a lock at the end. Lock 4 will allow rigidly fix the attached optical tube in channel 5. The other three channels are 6, two of which are working, one for irrigation. Work channels 6 are used for keeping medical instruments.

The device works as follows: after applying a milling hole, cut through the dura mater with a cruciform or arcuate incision. Next, point coagulation of the cerebral cortex is performed using a thermal dissector-sphere or scapula, to prevent bleeding. Connect the light cable to the optical tube and perform the correction parameters of the optics. Then the tube 1 with the obturator fixed in it is inserted into the cranial opening to a predetermined depth, having previously connected an aspirator irrigator to the tube 1 through one of the channels 5. Through the channel 6 in the tube 1 the optical device is turned on and the last device is fixed in the tube 1 by means of a lock 4.

After visualizing the anatomical landmarks and determining further tactics, endoscopic instruments are inserted through one of the instrumental channels 5. In this case, the tube 1 must be fixedly fixed with the help of a robot arm or a manipulator to the operating table. Due to this trauma when changing tools is reduced to zero, you can simultaneously work with two tools.

For example, in cysts of the ventricular system, forceps and scissors are inserted into the instrumental canals, which perforate and cut through the walls of the cyst, followed by laundering of liquid blood and soft clots through the irrigation canal. For a better view of the field operated, it is better to use an optical tube with an overview of 30 degrees.

The tube 1, which serves for the precise introduction of neurosurgical instruments in the operated field, is attached to the housing 3, which is intended for branching the instrumental channels 6 for comfortable operation of the operating surgeon. On the other side of the tube 1 is attached the head 2 (the tip of a rounded shape), designed to facilitate the passage of the tube through the brain tissue and reduce the possibility of damage to the vessels. Lock 4, rigidly fixing the attached optical tube, is connected to channel 5, designed for precise insertion of the endoscope into the operated field, after which they are fixed to body 3.

After prototyping and clinical testing, it will be possible to make additional adjustments, both in surgical procedures and in instrument designs. When using techniques with a new tube, you can perform some operations without an assistant, with the involvement of only the operating sister.

The claimed technical solution meets the requirement of industrial applicability and can be manufactured on standard equipment using modern materials and technologies.
