Description

The device relates to medicine, namely to surgery, angiology, traumatology, and can be used to fix attachments of various medical instruments.

Medical instruments used in surgical specialties have a handle and different versions of the working part, while the instrument handle often makes up the largest part of the instrument and is the most material-intensive.

The prototype of the fixator for attachments of medical instruments is the Fixator for attachments of medical instruments (Patent of the Russian Federation for utility model No. 193293 dated 2019).

The disadvantage of the prototype is the free location from the fixation unit of the working nozzles of the plate retainer, which is small and when assembling the sterile device itself in the operating room there are technical inconveniences, at the same time it is necessary to fix (fix) the retainer sleeve and the nozzle of the working tool. During operation of this version of the latch, the working nozzle can come out of the latch sleeve and it is necessary to hold it in the required position by the surgeon's hand, which is inconvenient.

EFFECT: creation of a device for fixing replaceable nozzles of medical instruments with a simplified method of fixing and extracting them by creating a non-separable fixation unit.

The technical result is achieved due to the presence in the device of the fixation unit for working nozzles in the form of a cylindrical sleeve with a diameter of 8.0 mm, a length of 20.0 mm, characterized in that the fixation unit is made non-separable with an internal chamber for nozzles of medical instruments, with a diameter of 3.0 mm, moreover, on the outer surface of the nozzle fixation unit in the projection of the handle plane there is a flat edge for locating the retainer plate with a hole, in the distal part of the flat edge of the fixation unit 2.5 mm from the end of the sleeve there is a hole for the pin of the working attachment fixator; the spring latch is a steel plate 19.0 mm long, 6.5 mm wide, 1.5 mm thick, movably fixed on an axis 3.0 mm in diameter, with a head 5.0 mm in diameter, located in the proximal part of the flat face of the sleeve; on the distal edge of the fixation plate, in the projection of the hole in the sleeve, there is a fixator pin with a diameter of 2.5 mm, a length of 3.0 mm; on the outer side of the fixing plate, in the projection of the pin, a U-shaped bracket 1.5 mm wide, 6.5 mm long, 4.0 mm high is located transversely to remove the fixator pin from the working nozzle and then remove the nozzle from the fixation unit.

The utility model is illustrated by figures (Fig. 1-2).

In FIG. 1 is a view of the device in the open position of the spring latch, frontal projection.

In FIG. 2 is a view of the device in the closed position of the spring latch, frontal projection.

The device consists of a shaped handle (1) of an elongated drop-shaped configuration 85.0 mm long and a fixation unit for working nozzles (2) in the form of a cylindrical sleeve with a diameter of 8.0 mm, a length of 20.0 mm, characterized in that the fixation unit is made non-separable with an internal chamber for nozzles of medical instruments (3), with a diameter of 3.0 mm, and on the outer surface of the nozzle fixation unit in the projection of the plane of the handle there is a flat edge (4) for locating the retainer plate with a hole (5), in the distal part of the flat edge of the fixation unit by 2 .5 mm from the end of the sleeve there is a hole for the pin of the clamp of working nozzles (6); spring retainer (7) is a steel plate 19.0 mm long, 6.5 mm wide, 1.5 mm thick, movably fixed on an axis (9) 3.0 mm in diameter, with a head 5.0 mm in diameter, located in the proximal part of the flat face of the sleeve; on the distal edge of the fixation plate, in the projection of the hole in the sleeve, there is a fixator pin, 2.5 mm in diameter, 3.0 mm long; on the outside of the fixator plate, in the projection of the pin, a U-shaped bracket (8) 1.5 mm wide, 6.5 mm long, 4.0 mm high is located transversely to remove the fixator pin from the working nozzle and then remove the nozzle from the fixation unit .

The device works as follows.

After lifting the spring retainer by the U-shaped bracket with any clamp, the necessary working nozzle of the medical instrument is inserted into the sleeve of the fixation unit for the working nozzles of medical instruments with the hole for the lock pin upwards. After using the tool, the working nozzle is removed after lifting the spring retainer by the U-shaped bracket with any clamp.

Examples of clinical application of the device

The fixator of attachments of medical instruments, used in combination with the working attachments "Ligature Dissector", "Fenestrated Surgical Speculum" and "Fenestrated Raspator", was used in 26 clinical cases.

Patient A., 59 years old, was hospitalized at the Regional Clinical Hospital for Emergency Medical Services in Kursk from 03/07/2022 to 03/14/2022. Diagnosis: acute calculous phlegmonous cholecystitis. On 03/08/2022, an open cholecystectomy and drainage of the abdominal cavity were performed.

Under intravenous anesthesia, after triple treatment of the surgical field with iodopyrone, an entrance to the abdominal cavity was made using an oblique incision in the right hypochondrium up to 10 cm. Using a fixator for attachments of medical instruments and a nozzle "Finated surgical mirror", hemostasis of the abdominal wall was performed by diathermocoagulation and ligation of individual vessels. On examination of the abdominal cavity: the liver is slightly enlarged, the edge is rounded. Gallbladder with signs of phlegmonous inflammation, dimensions 110.0 × 43.0 × 32.0, wall 4 mm thick, blocking calculus up to 20.0 mm in the neck. Puncture of the gallbladder yielded purulent bile up to 50 mm. The cystic duct and artery were isolated, ligated and transected. The gallbladder is isolated from the bed and removed. The gallbladder bed was sutured with catgut thread. Control of bile and hemostasis, dry. Sanitation and drainage of the abdominal cavity. Layered wound closure. Aseptic bandage. There were no postoperative complications associated with the use of the new medical instrument. The sutures were removed on the 8th day. The patient was discharged from the department on the 10th day after the operation in a satisfactory condition, under the supervision of a surgeon at the place of residence.

Patient I., 70 years old, was hospitalized at the BMU "KOKB" in Kursk from 03/25/2022 to 04/11/2022. Diagnosis: postoperative ventral hernia of the anterior abdominal wall. On March 28, 2022, hernioplasty was performed with mesh implant arthroplasty using the onlay technique.

Under endotracheal anesthesia, after triple treatment of the surgical field with iodopyrone, excision of a skin area in the projection of the hernial protrusion was performed. The hernial sac and edges of the aponeurosis around the hernial orifice were isolated using a fixator for the attachments of medical instruments and a working attachment "Finated raspator". Using the "Mirror fenestrated" hemostasis of the wound of the abdominal wall was performed. After opening the hernial sac, enterolysis of the small intestine was performed. The hernial sac was excised up to the hernial orifice. The edges of the mobilized aponeurosis of the anterior abdominal wall were sutured and endoprosthesis was performed with a mesh implant measuring 16×10 cm using the onlay technique. The fixation of the implant with a continuous suture along the perimeter of the defect, as well as with additional fixation with interrupted sutures to the aponeurosis, was performed with a Polypropylene thread. The subcutaneous adipose tissue was drained with tubular drainage. When using these useful models, the time for hemostasis and the duration of the operation were reduced. There were no postoperative complications with the use of new instruments. The drain was removed on the second day after surgery. The sutures were removed 14 days after the operation. Discharged for outpatient aftercare at the place of residence under the supervision of a surgeon.

Patient O., 48 years old, was hospitalized at the BMU "KOKB" in Kursk from 05/02/2022 to 04/11/2022. Diagnosis: acute calculous cholecystitis. On May 3, 2022, an open cholecystectomy was performed with the installation of a tubular drainage.
