Abstract
Description
Technical Field
[0001] This utility model relates to the field of laparoscopic surgical instruments, and in particular to a laparoscopic ice slurry stirring injector. Background Technology
[0002] In laparoscopic partial nephrectomy, a lot of ice is often added around the kidney to further reduce the metabolic rate of the kidney tissue. This reduces the metabolic rate of the kidney, decreases intraoperative bleeding, facilitates the removal of the lesion and the suturing and hemostasis of the removed kidney tissue, preserves kidney function to a greater extent, promotes postoperative recovery, and shortens hospital stay. However, due to the lack of suitable tools for pushing ice into the abdominal cavity, four syringes are currently used to inject ice into the abdominal cavity. This is not only slow and extremely cumbersome, but also time-consuming, making it difficult to reduce intraoperative bleeding and shorten operation time, and the effect is very poor, which is not conducive to postoperative recovery. Doctors and nurses often experience hand pain and coldness after injecting ice. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a laparoscopic ice slurry stirring and injecting device, which has the function of stirring to prevent ice slurry from condensing and agglomerating, while also having the function of transporting ice slurry and preventing abdominal air leakage.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a laparoscopic ice slush stirring injector, including a channel, a hopper, spiral blades and a mandrel;
[0005] The upper end of the channel is connected to the outlet end of the hopper;
[0006] The spiral blade is rotatably fitted inside the channel. The upper end of the spiral blade is coaxially fixed with the lower end of the mandrel. A handle is provided at the upper end of the mandrel.
[0007] When in use, the outlet of the channel is connected to the abdominal cavity. Place the ice slush in the hopper, and drive the spiral blades to rotate by the handle. The rotation of the spiral blades can transport the ice slush downwards, thus easily transporting the ice slush into the abdominal cavity.
[0008] Preferably, the outlet end of the channel is connected to a flexible tube to facilitate communication with the abdominal cavity.
[0009] Preferably, the flexible tube is made of silicone. This makes it more flexible and easier to bend and connect to the abdominal cavity.
[0010] Preferably, a one-way valve is provided inside the hose to prevent gas from flowing out of the abdominal cavity.
[0011] Preferably, the one-way valve includes two elastic valve plates, the outer ends of which are fixed to the inner wall of the hose, and the inner ends of which are pressed together inward. This effectively enables the slush to flow unidirectionally within the hose.
[0012] Preferably, the hopper is provided with an inner support, and the mandrel is rotatably engaged with the inner support. This improves the stability of the handle driving the spiral blades to rotate.
[0013] Preferably, the mandrel is provided with conical spiral blades whose outer diameter is adapted to the hopper. That is, there are also spiral blades inside the hopper, which facilitates the improvement of the conveying capacity of ice slush.
[0014] Preferably, the upper end of the hopper is provided with a cover plate, the cover plate comprising two halves, and the two halves of the cover plate having notches corresponding to the mandrel. This prevents the ice slush from flowing out during agitation.
[0015] The beneficial effects of this utility model are:
[0016] The spiral blades provide stronger conveying power, delivering the slush more stably into the abdominal cavity, and making operation more convenient. They also agitate the slush to prevent it from clumping together, transport it, and prevent air leakage from the abdominal cavity. Attached Figure Description

[0020] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.
[0021] Example
[0022] like Figure 1As shown, the laparoscopic ice slush agitator includes a channel 3, a hopper 1, a spiral blade 2, and a mandrel 7; the upper end of the channel 3 is connected to the outlet end of the hopper 1; the spiral blade 2 is rotatably fitted inside the channel 3, the upper end of the spiral blade 2 is coaxially fixed with the lower end of the mandrel 7, and a handle 9 is provided at the upper end of the mandrel 7.
[0023] When in use, the outlet of channel 3 is connected to the abdominal cavity. The ice shavings are placed in hopper 1, and the spiral blades 2 are rotated by handle 9. The rotation of the spiral blades 2 can transport the ice shavings downward, thus easily transporting the ice shavings into the abdominal cavity.
[0024] The outlet end of the channel 3 is connected to a flexible tube 4, which facilitates communication with the interior of the abdominal cavity.
[0025] The flexible tube 4 is made of silicone. It is more flexible and easier to bend and connect to the abdominal cavity.
[0026] A one-way valve 5 is installed inside the flexible tube 4 to prevent gas from flowing out of the abdominal cavity.
[0027] The one-way valve 5 includes two elastic valve plates. The outer ends of the two valve plates are fixed to the inner wall of the hose 4, and the inner ends of the two valve plates are pressed together inward. This allows for effective one-way flow of the slush within the hose 4.
[0028] The hopper 1 is equipped with an inner support, and the spindle 7 is rotatably engaged with the inner support. This improves the stability of the spiral blade 2 driven by the handle 9.
[0029] The mandrel 7 is surrounded by conical spiral blades 6 with an outer diameter adapted to the hopper 1. That is, there are also spiral blades 2 inside the hopper 1, which facilitates the conveying capacity of ice slush.
[0030] The upper end of the hopper 1 is provided with a cover plate, which consists of two halves, and the two halves of the cover plate are provided with notches corresponding to the mandrel 7. This is to prevent the ice slush from flowing out when agitated.
[0031] The beneficial effects of this utility model are:
[0032] The spiral blades 2 provide stronger conveying power, delivering the slush more stably into the abdominal cavity, making operation more convenient. They also agitate the slush to prevent it from clumping together, while simultaneously conveying it and preventing air leakage from the abdominal cavity.
[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0034] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
