Description

The utility model relates to medicine, namely to vascular surgery, and more specifically to devices that allow optimizing the storage and use of vascular probes during surgery, thereby reducing the risk of instrument desterilization, increasing the working area on the operating table of a nurse, reducing time spent on the insertion / extraction of probes during surgery.

The classic table of the operating sister is known, which is used when performing surgical operations (https://grandmedical.ru/operatsionnaya/stoliki-instrumentalnye/stol-operatsionnoj-sestry-ag-1).

Its disadvantages are the impossibility of full placement of vascular probes without bends; the need to bend the instrument, which can cause the instrument to fall off the table and be desterilized.

A device for intraoperative storage of laparoscopic instruments is known (RF patent No. 2176495, A61G 13/00, 10.12.2001), which contains a panel mounted on a rod. The panel is made in the form of a box, which is divided into compartments for filling with an antiseptic solution. The box is made of a transparent anti-corrosion material and fixed with the possibility of rotation in a vertical plane on the bar. The bar has a swivel mount.

Its disadvantages include the impossibility of full placement of vascular probes without bends; high risk of tipping on the floor and desterilization.

A known container for the sterilization of medical instruments (RF patent No. 3092, A61L 2/00, 11/16/1996), containing a body and a lid, which is made in a shape that encloses a medical instrument placed inside it, in the form of a split spring ring, which is equipped with a tubular ring in the center. ledge, at least two pointed pins are attached to the lower surface of the cover, directed towards the tool placed inside the cover, in which holes are made for placing pins in them, moreover, a guide screw is fixed inside the body in the center of the bottom, coaxially to which a clamping screw is placed inside the tubular protrusion of the cover. screw.

The disadvantages include too narrow base, which does not allow the use of vascular probes without difficulty in their extraction and positioning, which in turn increases the time of the surgical intervention.

Known surgical sterile tray for storage and use of surgical instruments (RF patent No. 2493796, A61V 19/02, 09/27/2013), including a pump, a drive, a surgical tray, a structure for attaching a sheet placed on top of the patient, and a structure that forms at least one groove for retaining liquid. The drive is connected to the pump. The groove provides a collection of fluid from the sheet during a surgical operation. The surgical tray has a surface that is designed to hold surgical instruments. The shape of the tray corresponds to the contour of the body part located next to the surgical field.

Its disadvantages include the fact that it is made technically complex and difficult to operate, the inability to use it for vascular probes during the operation without difficulty.

All of the above devices, in addition, have common drawbacks - they are not focused on surgical vascular instruments (probes); the need to position and reduce the length of the tool by bending and twisting, which in turn changes the configuration of the tool and increases the risk of breakage.

An analysis of existing devices for storing and using surgical instruments showed that none of them can be a prototype for the utility model proposed by the authors.

The task to be solved by the claimed utility model is to increase the convenience of work and reduce the risk of desterilization of vascular surgical instruments intraoperatively.

The technical result of the present invention is to provide free and unhindered intraoperative access to vascular probes, secure fixation in the immediate vicinity of the surgical access area and the surgeon, reduce the risk of desterilization of instruments and ensure storage of instruments without their deformation (bending and twisting).

This technical result is achieved by the fact that the device for intraoperative storage and use of vascular probes is a hollow cylindrical tube with a diameter of 5 cm, a length of 120 cm, the ends of which are sealed, on the side surface of the hollow cylindrical tube for its entire length and for 1/3 of its circumference, a slot for access to the instrumentation bed, oriented upwards, and on the other side of the hollow cylindrical tube, holes are made on its side surface for fixing the device on the operating table skids.

The device can be made of low density polyethylene (LDPE) or galvanized stainless steel with a thickness of 0.2-0.3 mm.

The utility model is illustrated by graphic material, where Fig.1 shows a general view of the device, made in the form of a hollow cylindrical tube 1, the ends 2 of which are sealed. On one side of the hollow cylindrical tube, a slot 3 is made for its entire length and 1/3 of its circumference for access to the instrumentation bed. Inside the hollow cylindrical tube there is a bed for laying vascular probes 5. On the other side of the hollow cylindrical tube 1, holes 4 are made on its side surface for fixing the device on the runners 6 of the operating table 7. In Fig. 2 shows an example of installing the device on the operating table 7, by fixing the device with holes 4 on the runners 6.

In practice, the device for optimizing intraoperative storage and use of vascular probes works as follows. Intraoperatively, the hollow cylindrical tube 1 is unpacked from the sterile package, with the help of junior medical personnel it is fixed through the holes 4 for fixation on the runners 6 of the operating table 7. The device is oriented with the slot 3 upwards to access the bed of the vascular probes 5 in the direction convenient for the surgeon. Sterile vascular probes 5 are placed in the bed of the device and they are used depending on the course and features of the surgical intervention.

The device for intraoperative storage and use of vascular probes allows you to freely change the size and reuse of vascular probes, reduces the risk of desterilization of instruments, levels damage to the probes associated with their bending and deformation.

The use of the device to optimize intraoperative storage conditions and the use of vascular probes is illustrated by a clinical example.

Patient R., aged 70, was admitted on an emergency basis to the Department of Vascular Surgery of the Regional Clinical Hospital with a diagnosis of acute thrombosis of the popliteal, anterior tibial, and posterior tibial arteries of the right lower extremity. Acute ischemia of the 26th degree of the right lower limb. After examination and preoperative preparation, an operation was performed: thrombectomy from the popliteal artery, arteries of the lower leg of the right lower limb, drainage of the postoperative wound. During the operation, a device was installed to optimize intraoperative conditions for storage and use of vascular probes on the operating table, and vascular probes were placed. An access was made through Ken's line on the upper third of the right tibia. The popliteal artery with a diameter of 5.5 mm was taken on holders, after its clamping, a transverse arteriotomy 3.5 mm long was performed 10 mm above the trifurcation. Fogarty probes 2f, 3f, 5f, previously located in the bed of the device, were alternately introduced and removed into the hole, thrombotic masses were removed, satisfactory antegrade and retrograde blood flow was obtained. When using the device, it was noted that the speed of manipulations increased and the risk of desterilization of the probes was significantly lower. The arteriotomy was sutured with interrupted sutures. No complications were observed in the postoperative period. The patient was discharged for outpatient treatment on the 9th day.
