Description

[0001] The utility model relates to the field of medicine and medical technology, namely surgery, and is intended for use in surgical interventions on the kidneys.

[0002] Today, various speculums produced by the medical industry are used during laparotomy procedures on urinary tract organs, particularly the kidneys. It should be noted that such instruments are typically non-detachable, which increases the bulk of the surgical kit needed to transport, for example, to mobile hospitals. The lack of an additional source of illumination for the surgical wound can complicate and prolong the procedure itself.

[0003] Thus, a collapsible surgical mirror is known [RU 170920 U1, IPC A61B 17 / 02, published 05 / 15 / 2017], consisting of a working part and a handle, characterized in that the working part of the device is made in the form of a mirror with a concave surface, equipped with a protrusion having a groove with a thread, and the fixation of the working part on the proximal end of the handle is carried out using a protrusion with a thread.

[0004] The disadvantage of this instrument is the lack of ability to additionally illuminate soft tissues in the surgical area.

[0005] A surgical retractor is known [WO 1999 / 56633, IPC A61B 17 / 00, A61B 17 / 02, A61B 19 / 00, published 11.11.1999], having a handle connected at an acute angle to a blade, and a connector for a light source.

[0006] Also known is a surgical retractor for deep pelvic surgery [US 6554768 B1, IPC A61B 17 / 00, A61B 17 / 02, A61B 19 / 00, published 04 / 29 / 2003], which has a handle connected at an obtuse angle to a blade, and a connector for illumination.

[0007] A renal mirror is known [RU 193406 U1, IPC A61B 17 / 02, published 28.10.2019], containing a working part in the form of a curved blade and a handle, wherein a two-wire electric wire is attached to it using staples, at one end of which there is an LED strip in a sealed silicone capsule located on the front surface of the curved blade, and at the second end there is a plug.

[0008] A common drawback of these devices, in addition to the lack of the ability to disassemble for compact storage and transportation, is the presence of a wire running to the backlight, which limits the surgeon's movements, often preventing the instrument from being positioned at the desired angle.

[0009] The objective of the utility model is to create a collapsible renal mirror with the possibility of compact storage and transportation, allowing for illumination of hard-to-reach areas of the surgical wound without restricting the operator's movements.

[0010] In the implementation of the utility model, the stated problem is solved due to the technical result, which consists in the possibility of quickly assembling a mirror with additional illumination of soft tissues during surgery.

[0011] The specified technical result is achieved by the fact that the renal mirror has a groove in the blade for securing the handle in which the LED light source is installed.

[0012] Fig. 1 shows a general view of the utility model.

[0013] Fig. 2 shows a blade 2.

[0014] Fig. 3 shows handle 1.

[0015] Fig. 4 shows an example of the position of a collapsible renal mirror in a surgical wound.

[0016] The disassemblable renal mirror is made of plastic and contains a handle 1, installed in a blade 2 through a groove 3 made in it up to the stops 4 of the handle 1, and a LED light source 5 with an on / off button 7, which is fixed in a hole 6 made along the axis of the stops 4 in the handle 1.

[0017] Light source 5 is represented by a housing, inside which there is a block for three batteries (for example, AG3), connected to an LED.

[0018] Handle 1 and spatula 2 are not suitable for independent use separately, as they are intended for use only when assembled.

[0019] The utility model is used as follows.

[0020] Before the operation, all parts of the disassemblable renal mirror are removed from the sterile packaging and connected so that the handle 1 passes through the groove 3 of the blade 2 until its surface comes into contact with the stops 4, and the LED light source 5 with the on / off button 7 is placed in the hole 6.

[0021] Then, after performing surgical access, the spatula 2 is inserted into the wound and the LED light source 5 is turned on by pressing the on / off button 7, and the operation proceeds to the next stage.

[0022] If necessary, during the surgical intervention, the operator can change the position of the handle 1, as a result of which the position of the blade 2 with the LED light source 5 changes, thereby achieving the required volume of access with illumination of soft tissues.

[0023] Once the operation is completed, the mirror is removed and subject to disposal.

[0024] The description of the utility model is supplemented by an example.

[0025] Case 1. Patient H., 24 years old. Diagnosis: Closed concomitant abdominal trauma. Crushing injury of the left kidney (grade IV according to AAST): multi-fragmentary rupture of the parenchyma involving the renal pelvis and calyces, extensive perirenal hematoma, massive hemorrhage into the retroperitoneal space. Macrohematuria. A decision was made to perform a laparotomic nephrectomy. After preparing the surgical field, a lumbotomy was performed under endotracheal anesthesia. The surgical nurse removed all parts of the disassemblable renal speculum from the sterile packaging, assembled them, and handed them to the surgeon. Spatula 2 was placed in the wound and held in position by holding handle 1. To provide additional illumination, LED light source 5 was turned on by pressing on / off button 7. The intervention was continued in accordance with the protocol. Before closure of the wound, the renal speculum was removed.

[0026] The design of the declared technical solution ensures not only ease of storage and transportation, but also improved visualization of the surgical field due to the presence of an LED light source, which provides a sufficient level of light in hard-to-reach places.

Claims

A collapsible renal mirror comprising a handle, a spatula and a LED light source, characterized in that the handle is installed in the spatula through a groove made therein up to the handle stops, while the handle is made with an opening in which an LED light source with an on / off button is installed.
