Description

The utility model relates to medical equipment, to X-ray equipment used in operating rooms, and is intended for X-ray monitoring during surgical operations on the torso and proximal limbs, namely to ensure rapid insertion of an X-ray cassette under the examined part of the patient’s body and its subsequent removal.

Under normal conditions, when performing radiography of body organs, for example, in traumatology and orthopedics - images of the collarbone, scapula, spine, hip or shoulder joints, the X-ray cassette is placed under the corresponding area of study. To do this, the operating surgeons have to lift this part of the body at the time of insertion and removal. Such lifting of the torso of a patient under anesthesia is physically difficult work, since the patient can have a fairly large body weight, and surgeons have to do this in conditions where the patient’s body is covered with sterile sheets and the cassette is unsterile. Covering the cassette with sterile material is applicable for intraoperative X-ray control of the middle or distal limbs, when the sterile limb can be elevated and the cassette covered with sterile material placed between the sterile surface of the operating table and the sterile (treated and covered) limb. With radiography in the torso area, this is impossible (the back and lower back lying on the operating table are unsterile), it is very difficult physically and threatens to disrupt the sterility of the surgical fields.

A known cassette holder is built into the operating X-ray table [1]. The cassette holder is a flat box the size of the cassette with fasteners, suspended on carriages that ensure the movement of the cassette holder together with the cassette to a given location under the radiolucent surface of the table. The disadvantage of such devices is the very high price of the entire X-ray operating table with cassette holder and design complexity.

A known device is a “radiotransparent table with a cassette holder” used in veterinary medicine [2]. The device was chosen as a prototype because it contains a cassette receiver with a cassette niche in which an X-ray cassette is placed during the study and, by moving the cassette receiver together with the cassette under the area under study, an x-ray is taken, after which the cassette is removed. In veterinary practice, such a table can be used to operate and take radiographs. The disadvantage of the device is the lack of functionality of a modern operating table and its inapplicability in hospitals equipped with multifunctional operating tables that do not have X-ray cassette receivers.

The objective of the utility model is to develop a device that allows access under the examined part of the patient's body for inserting an X-ray cassette for radiography on any operating table, free of the above-mentioned disadvantages.

The technical result of the utility model is to provide the ability to perform radiography during surgery without disturbing the patient's position and the sterility of the surgical fields with ease of use.

The technical result of the claimed utility model is achieved by the fact that the cassette receiver for intraoperative X-ray monitoring includes a radiolucent body and a niche for inserting a cassette into it; according to the utility model, it contains rectangular convex and flat surfaces, rigidly connected by seams along two opposite edges, thereby forming a through niche for cassettes, the width of the cassette receptacle is equal to the width of the operating table, each seam has a spacer with a thickness equal to the thickness of the cassette, and the length of the niche is equal to the length of the cassette, and the mentioned dimensions of the niche are made with tolerances that ensure the possibility of unhindered insertion and removal of the cassette from it.

The illustrations show

Figure 2 - cassette receiver for intraoperative X-ray control on the operating table, side view (a cassette is inserted into the niche of the cassette receiver), where: 1 - convex radiolucent surface, 2 - flat radiolucent surface, 3 - niche for the cassette, 4 and 5 - seams, fixing surfaces 1 and 2 between each other, 6 - operating table, 7 - cassette.

Figure 3 - cassette receiver for intraoperative X-ray control, side and top view (a cassette is half inserted into the niche of the cassette receiver), where: 1 - convex radiolucent surface, 2 - flat radiolucent surface, 3 - niche for the cassette, 4 and 5 - seams, fixing surfaces 1 and 2 between each other, 6 - operating table, 7 - cassette.

Figure 4 - cassette receiver for intraoperative X-ray control, side view (cassette 7 is inserted into the niche of the cassette receiver, patient 8 is undergoing examination of the cervical spine), where: 1 - convex radiolucent surface, 2 - flat radiolucent surface, 3 - niche for the cassette, 4 and 5 - sutures fixing surfaces 1 and 2 to each other, 6 - operating table, 7 - cassette, 8 - patient.

The cassette receiver (Fig. 1-4) for intraoperative X-ray control is made of radiolucent material and contains rectangular convex 1 and flat surfaces 2, between which there is a through niche 3 for the cassette 7.

The convex 1 and flat 2 surfaces are rigidly connected by seams 4, 5 along two opposite edges of the cassette receptacle. Each seam 4, 5 has a spacer (insert, liner) with a thickness (from the side of the niche 3) equal to the thickness of the cassette 7 with the condition that it 7 passes freely (with tolerance), which allows the cassette 7 to be easily inserted into the niche 3 and removed from it 3. The width of the cassette receiver, respectively, the width of the surfaces 1, 2, as well as the width of the niche 3, is equal to the width of the operating table 6, which does not disturb the position of the patient 8 and makes it easier for the x-ray technician to find a niche 3 for the cassette 7 and insert the 3 x-ray cassette 7 into it. Convex 1 and flat 2 surfaces, rigidly connected at the edges by seams 4 and 5 with spacers, when pressure is applied to them by the weight of the patient’s torso 8, also due to their shape, they come into a stressed-strain state, which prevents deformation of surfaces 1 and 2 framing the niche 3 and provides it 3 has a constant lumen height for insertion and removal of the X-ray cassette 7. Its 3 length (from spacer to spacer) is made along the length of the 3 X-ray cassette 7 inserted into it with the possibility of its free insertion and removal (with tolerance) from the niche 3. Both surfaces 1 and 2 are radiolucent, which allows radiography to be performed on both sides (surfaces) of the device. Depending on the anatomical area being studied, to maintain the patient’s position on the operating table, the cassette receiver is placed on the table under the torso or limbs with a convex 1 or flat 2 surface. For example, when examining the lower back or neck, the convex surface 1 is oriented upward, respectively, the flat surface 2 is placed on the operating table, and when examining the pelvis, hip joints, shoulder blades, shoulder joints and collarbone, the flat surface 2 is oriented upward.

The device is used as follows. Before placing the patient 8 on the operating table 6, under the part of the body that is to be operated on and monitored using radiography, a cassette receiver for intraoperative x-ray control is placed so that the cassette niche 3 is oriented across the operating table 6, and sutures 4 and 5 are located cranial and caudal to the anatomical region under study. Through the through niche 3, it is possible to insert and remove the cassette 7 from both the right and left sides of the operating table 6.

After treating the surgical fields, covering with sterile material, as well as performing the main stage of the operation, for X-ray control, lift the edge of the sterile sheet hanging from the table and insert cassette 7 into niche 3, perform radiography, after which, by also lifting the edge of the sterile sheet, remove the cassette 7 from niche 3. Surgeons with a sterile hand lift the edge of the sterile sheet, and the radiographer with a non-sterile hand first inserts the cassette 7 into niche 3, and then removes the 3 non-sterile cassette 7 from it. At the same time, they do not apply physical force to the patient’s body 8 and do not disturb the location of the sterile material on the operated area.

The device allows you to quickly and without physical effort place the cassette under the part of the patient’s body being examined, take an x-ray, and also easily remove the cassette without disturbing the patient’s position while maintaining the sterility of the surgical field.
