Description

Operating table suitable for delicate surgery on the lower back of rats

technical field

The invention relates to an operating table suitable for fine surgery on the lower back of rats, and is suitable for performing fine operations on the lower back of rats (such as nerve and small blood vessel operations).

Background technique

With the deepening of research in the field of neuropathic pain science, more and more experimental studies have been conducted on the anatomy of the lower back nerves of experimental animals and the observation of the activation of substances related to pathological pain and their relationship under the pathological state of nerve ligation or cutting. However, the existing rat operating table cannot expose the rat lumbar and back operation site well, nor can it provide a broad surgical field of vision for this type of fine surgery. There is an urgent need for an operating table suitable for rat lumbar and back fine surgery. To solve the experimental operation problems of fine surgery on the lower back of rats.

Contents of the invention

The purpose of the present invention is to provide an operating table suitable for fine surgery on the lower back of rats aiming at the deficiencies of the prior art.

The purpose of the present invention is achieved through the following technical solutions: an operating table suitable for fine surgery on the back of rats, comprising an arched base plate and a bottom bracket, the arched base plate is composed of two opposite arc-shaped slopes, located It is composed of an intermediate platform between two curved slopes and smoothly connected with the top of the two curved slopes, and a bottom platform smoothly connected with the bottom of the curved slope; the bottom bracket is connected with the bottom platform; the middle of each curved slope is open There are two side-by-side square notches, and a plurality of limb fixing hooks are fixed on both sides of the square notch; the bottom bracket includes an elastic rubber ring, a polished rod, a sleeve, a screw rod and a bottom supporting platform in sequence from top to bottom; the sleeve The barrel has an internal thread matched with the screw, the upper end of the sleeve is fixedly connected with the polished rod, the lower end of the screw is fixedly connected with the bottom support platform, the elastic rubber ring is interference fit with the polished rod; the bottom platform has an aperture larger than the polished rod and smaller than the sleeve The round hole on the outer diameter of the barrel, the polished rod passes through the round hole, and the bottom platform is located between the elastic rubber ring and the sleeve.

Further, it also includes an LED lamp and an LED lamp bracket, and the LED lamp is fixed on the middle platform through the LED lamp bracket.

Further, it also includes a gas delivery cannula fixing device fixed on one side of the middle platform, the gas delivery cannula fixing device is composed of an upper adjustment screw and a C-shaped fixer, and the upper adjustment screw is threadedly connected to the top of the C-shaped fixer .

Further, the middle platform is a stainless steel plate with a length of 30cm and a width of 8cm, and the height from the bottom platform is h; the horizontal distance between the middle platform and the bottom platform is L, satisfying The bottom platform is a stainless steel plate with a length of 30cm and a width of 5cm; a square notch is 4cm in length and 1cm in width.

The beneficial effect of the invention is that the advantage of better exposure of the surgical site can be achieved by adjusting the shape of the platform without increasing the pain of the rats. When the rat is placed on the arched operating table, the raised platform in the middle raises the surgical site, and the slopes on both sides generate moderate tension, which is conducive to better exposure of the surgical site, separation of small internal blood vessels and nerves, and clear surgical area exposed. The equipped LED light is directly fixed on the operating table, which is beneficial to the operation of delicate operations (nerve, blood vessel ligation, etc.), and the angle of the light source is easy to adjust during the operation, which is convenient for operation. The equipped bottom bracket can be adjusted in height according to the operator's habit, which is convenient for operation. The equipped gas delivery intubation fixing device can fix the delivery of gas (oxygen, anesthesia gas) given to rats during surgery.

detailed description

As shown in Fig. 1, a kind of operating table suitable for fine operation of rat lumbar back, comprises arch base plate 1 and bottom support 2, as shown in Fig. 2, described arch base plate 1 is composed of two opposite arcs The slope 12, the middle platform 11 (located between the two curved slopes 12 and smoothly connected with the tops of the two curved slopes 12), and the bottom platform 13 (smoothly connected with the bottom of the curved slope 12); the bottom bracket 2 and the bottom The platforms 13 are connected; each arc-shaped slope 12 has two side-by-side square notches 14 in the middle for fixing the surgical retractors and exposing the surgical area; both sides of the square notches 14 are fixed with a plurality of limb-fixing retractors 15 .

As shown in Figure 3, the bottom bracket 2 includes an elastic rubber ring 25, a polished rod 24, a sleeve 23, a screw 22, and a bottom support platform 21 from top to bottom; Thread, the upper end of the sleeve 23 is fixedly connected with the polished rod 24, the lower end of the screw rod 22 is fixedly connected with the bottom support platform 21, the elastic rubber ring 25 is interference fit with the polished rod 24; the bottom platform 13 has an aperture larger than the polished rod 24 and smaller than the sleeve There is a circular hole in the outer diameter of the barrel 23, the polished rod 24 passes through the circular hole, and the upper side of the bottom platform 13 is located between the elastic rubber ring 25 and the sleeve 23. By rotating the sleeve 23, the height of the operating table can be adjusted.

The above-mentioned device may also include an LED lamp and an LED lamp bracket, not shown in the figure, and the LED lamp is fixed on the right side of the front end of the middle platform 11 through the LED lamp bracket. It is used to illuminate the delicate nerves, blood vessels and other structures inside the surgical site.

The above-mentioned device may also include a gas delivery intubation fixing device fixed on the left side of the front end of the intermediate platform 11, as shown in FIG. , the upper adjustment screw 41 is threadedly connected with the top of the semicircular fixer 42, and is used to fix the delivery of gas oxygen and anesthetic gas given to the rat during the operation.

The middle platform 11 is a stainless steel plate with a length of 30 cm and a width of 8 cm, and the height from the bottom platform 13 is h; the horizontal distance between the middle platform 11 and the bottom platform 13 is L, satisfying The bottom platform 13 is a stainless steel plate with a length of 30 cm and a width of 5 cm; the length of the square gap 14 is 4 cm and a width of 1 cm. It is conducive to the moderate inclination of the operating table to obtain sufficient support to expose the surgical area, so as to ensure the smooth operation of the rat's lumbar back fine operation, and to ensure that the rat is relatively comfortable during the entire operation without affecting the operation position to ensure animal welfare.

The method of use is as follows: the rat is placed in the prone position, the torso is placed on the middle platform 11, the limbs are fixed on the corresponding fixed hooks 15 by rubber bands, and the fixed hooks 15 at a suitable position are selected according to the required degree of tightness, and the gas delivery tube is intubated. Place it in the semicircular fixer 42, turn the upper adjustment screw 41 to fix the gas delivery tube on the semicircular fixer 42, keep the ventilation during the operation, and fix the other end of the small retractor on the two The side-by-side square notches 14 generate continuous tension. After the LED lights are powered on through the power cord, the light source is adjusted to be concentrated in the operation area according to the needs of the experiment. The bottom bracket 2 can be adjusted by adjusting the sleeve 23 according to the needs of the experimenter, and it can be rotated clockwise. The height of the sleeve 23 is reduced; on the contrary, the height is increased. After the above operations are completed, fine surgery on the chest and back can be performed.
