An intraoperative negative pressure suction device

Abstract

The present invention discloses an intraoperative negative pressure suction device, which includes a drainage member and a trough-shaped base. The trough opening of the base faces upward and is horizontally arranged in the left-right direction. An aspiration tube interface communicating with its interior is provided on the front side of the base. The drainage member is arranged at the trough opening of the base and is used to drain blood into the base. The aspiration tube interface is used to communicate with an aspiration tube. Thus, during vascular anastomosis, the intraoperative negative pressure suction device is placed in the surgical field, and the vascular stump ends are placed on the drainage member for anastomosis. In this way, the blood around the vascular stump will seep into the base and be sucked away through the aspiration tube, which can avoid blood stasis around the vascular stump and affect the clarity of the surgical field, and improve the surgical efficiency.

Description

Technical Field

[0001] The present invention belongs to the field of vascular anastomosis instruments, and particularly relates to an intraoperative negative pressure aspirator. Background Art

[0002] In plastic surgery, microsurgical vascular anastomosis is often required. Such anastomosis is usually performed under direct vision / microscope. During the operation, bleeding from surrounding tissues or vascular stumps may occur, affecting the surgical field of view, making the operation difficult, thus making the hemostasis operation more difficult, forming a vicious cycle, and reducing the surgical efficiency. Traditional negative pressure aspirators are tubular structures with holes or side holes at the front end. During the operation, the position needs to be continuously moved to suck out the exuded blood, and this tubular aspirator needs to be accurately aspirated to achieve the ideal effect, which is difficult for the assistant to achieve in microsurgery.

[0009] The beneficial effect of the above technical solution is as follows: Thus, the blood in the base can be drained away in time.

[0010] In the above technical solution, the base is fan-shaped with its arc opening facing forward.

[0011] The beneficial effects of the above technical solution are as follows: In this way, the blood in the base all gathers towards the inner side of the corresponding arc of the base, which facilitates the rapid discharge of the blood in the base.

[0012] In the above technical solution, an arc-shaped groove is recessed along the bottom edge of the front side of the bottom wall of the base groove along the bottom edge of the front side groove wall of the base, and the suction tube interface communicates with the inside of the arc-shaped groove.

[0030] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. In the following paragraphs, the present invention is described more specifically by way of example with reference to the accompanying drawings. The advantages and features of the present invention will be clearer according to the following description and the claims. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for the purpose of facilitating and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0031] Embodiment 1

[0032] As Figure 1 shown, this embodiment provides an intraoperative negative pressure suction device, including a drainage member 1 and a trough-shaped base 2. The base 2 has its trough opening facing upward and is horizontally arranged in the left-right direction. The front side of the base 2 is provided with a suction tube interface 22 that penetrates through its interior. The drainage member 1 is arranged at the trough opening of the base 2 and is used to drain blood into the base 2. The suction tube interface 22 is used to communicate with the suction tube 3. In this way, during vascular anastomosis, the intraoperative negative pressure suction device is placed in the surgical field, and the vascular stump ends are placed on the drainage member for anastomosis. In this way, the blood around the vascular stump will seep into the base and be sucked away through the suction tube, which can avoid blood stasis around the vascular stump and affect the clarity of the surgical field, and improve the surgical efficiency.

[0033] In the above technical solution, the base 2 is made of silica gel, latex or a flexible plastic member, so as to avoid damage to the patient's tissue.

[0034] In the above technical solution, the connection between the suction tube interface 22 and the base 2 is located at the lower end of the middle part of the front side wall of the base 2, so that the blood in the base can be drained away in time.

[0035] In the above technical solution, the base 2 is fan-shaped with its arc opening facing forward, so that the blood inside the base gathers towards the inner side of the corresponding arc of the base, facilitating the rapid discharge of the blood inside the base.

[0036] As Figure 2 shown, in the above technical solution, an arc-shaped groove 21 is recessed along the bottom edge of the front side of the bottom wall of the groove of the base 2 along the bottom edge of the front side groove wall of the base 2, and the suction tube interface 22 communicates with the inside of the arc-shaped groove 21, so as to further improve the discharge speed of the blood inside the base; or as Figure 3 shown, in the above technical solution, the inner bottom wall of the base 2 is an inclined surface, and the lowest point of its horizontal height is close to the connection point of the suction tube interface 22 and the base 2, so as to further improve the discharge speed of the blood inside the base.

[0037] In the above technical solution, the drainage member 1 is a mesh structure, which covers the notch of the base 2, has a good lifting effect, and the blood can conveniently seep down through the holes of the drainage member.

[0038] Embodiment 2

[0039] As Figure 4 and Figure 5 shown, in the above technical solution, the drainage member 1 includes a plurality of support rods 11. The plurality of support rods 11 are all arranged in the front-back direction and are spaced apart in the left-right direction. Both ends of each support rod 11 are connected to the upper ends of the front and rear side groove walls of the base 2, and it has a good lifting effect.

[0040] In the above technical solution, a groove 111 is recessed in the upper end of the support rod 11 along its length direction. Both ends of the groove 111 are close to the two ends of the corresponding support rod 11. A plurality of through holes 112 penetrating up and down are arranged at intervals along the length direction of the bottom wall of the groove 111, so as to facilitate the rapid discharge of the blood on the support rod into the base.

[0041] In the above technical solution, the plurality of support rods 11 are all distributed radially along the base 2 in the front-back direction, so that the plurality of support rods are orderly distributed at the upper end of the base.

[0042] The suction tube interface of the intraoperative negative pressure aspirator provided in Embodiment 1 and Embodiment 2 is connected to the suction tube (the other end of the suction tube is connected to a negative pressure device). At this time, the base is in a negative pressure state to suck away the blood inside the base in time. The drainage member is in a hollow structure at the upper end of the base, providing a support platform for the anastomosis of the blood vessel ports, and at the same time can timely discharge the blood oozing from the blood vessel ports into the base, thereby ensuring a clear surgical field, shortening the surgical duration, and improving the surgical efficiency and success rate.
