[0001] The utility model relates to planing operation washing suction steady voltage device technical field, especially planing cavity automatic constant pressure operation power device. BACKGROUND

[0002] Current operation planing system has two kinds, one does not have negative pressure suction, one is self-contained negative pressure suction, the two kinds of existing operation planing system all need to connect the flushing equipment when operating, and water is sprayed into the human cavity, and the water inflow and water pressure are controlled through the external equipment, when the water inflow and pressure are not enough, the human cavity collapses after the planing suction pressure relief, the operation visual field is lost, and operation accidents are prone to occur, when the water inflow and pressure are too large, the planing cutting has a wound, and the flushing liquid is pressed into the wound under excessive pressure, which can cause water poisoning and cause life danger to the human body.

[0003] The existing equipment is connected with the flushing device or the suction device with the pressure detection device, and the pressure of the human cavity needs to be adjusted artificially to keep the pressure in a safe range. The operation is relatively complicated, and the pressure is prone to be too high or too low. CONTENT OF THE UTILITY MODEL

[0004] The utility model discloses a planing cavity automatic constant pressure operation power device to solve the shortcomings in the prior art.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme: the planing cavity automatic constant pressure operation power device, including host computer, planing handle and planing tool, trolley, flushing liquid support, negative pressure bottle and silica gel pipe. The bagged flushing liquid is configured on the flushing support and is connected with the peristaltic pump to be transported to the human body through the host computer control, the negative pressure bottle is configured on the trolley and is connected with the host computer suction pump and planing handle for collecting the lesion tissue and waste liquid removed during operation, the host computer is equipped with the peristaltic pump and suction pump, and the peristaltic pump and suction pump are arranged on the outside and inside of the host computer respectively, the peristaltic pump and suction pump are all embedded with pressure detection devices, the bagged flushing liquid is communicated with the peristaltic pump through the silica gel hanging, and then is communicated with the endoscope water inlet, the negative pressure bottle gas outlet is connected with the host computer suction pump interface through the silica gel pipe, and the negative pressure bottle air inlet is connected with the planing handle through the silica gel pipe.

[0006] The aforementioned components achieve the following effects: When removing lesions, the bagged irrigation solution is connected to the peristaltic pump. The pump is then activated, automatically adjusting the irrigation water pressure according to the suction pressure set by the main unit. This allows the irrigation solution to be injected into the body through the endoscope's water injection channel for rinsing. Simultaneously, the negative pressure bottle draws out the removed lesions and waste fluid from the planer handle through the negative pressure generated by the main unit's suction pump. Pressure detection devices on both the peristaltic pump and the negative pressure pump control the balance between the water injection pressure and the suction pump's suction pressure, ensuring a constant water pressure within the surgical environment. This prevents collapse of the body cavity, loss of surgical vision, and surgical accidents caused by excessive suction. Furthermore, excessive pressure or high volume of water can lead to wounds during planing and cutting, and excessive pressure can cause water intoxication, posing a life-threatening risk.

[0007] When the suction power of the suction pump is increased, resulting in a larger water output and insufficient pressure within the body cavity to allow for collapse, the main unit automatically controls the peristaltic pump's irrigation speed to increase the injected water volume. Conversely, when the suction power of the suction pump is decreased, resulting in a smaller water output and excessively high pressure within the body cavity, the main unit automatically controls the peristaltic pump's irrigation speed to reduce the injected water volume, ensuring a constant pressure difference between the inlet and outlet water, and stabilizing the pressure within the surgical space within the body cavity within a reasonable range. This automatic water pressure balancing function prevents excessively high or low pressure at the surgical site by repeatedly adjusting the irrigation and suction pressures.

[0008] Preferably, the main unit also has an operating interface. The operating interface is used to adjust the working mode, rotation speed, suction force of the negative pressure pump, and flushing flow rate and pressure of the peristaltic pump.

[0009] The inlet and outlet water pressure difference that needs to be maintained during surgery can be preset in advance through the operation interface. If the water pressure is not suitable due to individual cases during the operation, it can also be adjusted directly through the operation interface. At the same time, the irrigation and aspiration operations are carried out on one machine, avoiding the need to operate back and forth with ordinary irrigation and aspiration equipment, thus optimizing the operation time and surgical risks and streamlining the surgical process.

[0010] Specifically, the main unit also has a foot switch interface. This interface connects to a foot switch, which controls the rotation of the planing tool motor and the negative pressure suction.

[0011] Preferably, it also includes a trolley, on which the main unit is disposed, the negative pressure bottle is fixed, and the flushing fluid holder is fixed.

[0012] Preferably, the trolley also includes a storage box.

[0013] Preferably, the trolley is equipped with four casters at the bottom, which are located at the four corners of the bottom of the trolley.

[0014] The setting of the trolley can facilitate the carrying and moving of the main machine and the negative pressure bottle, and the setting of the trolley facilitates the dismounting and fixing of the negative pressure bottle, thereby providing convenience for cleaning and replacing parts of the subsequent machine.

[0015] The storage box can be used to place equipment accessories, so that the accessories can be conveniently connected during the operation and stored after the operation.

[0016] Compared with the prior art, the advantages and positive effects of the utility model lie in that, in the utility model, when the lesion tissue is planed and cut, the irrigation liquid is connected to the peristaltic pump, the peristaltic pump is started, the peristaltic pump automatically adjusts the irrigation perfusion pressure according to the suction pressure set by the main machine, drives the irrigation liquid to be injected into the body through the water injection port of the endoscope for irrigation, and the negative pressure bottle sucks out the irrigated tissue and waste liquid from the planing handle through the negative pressure generated by the suction pump of the main machine; the pressure detection devices on the peristaltic pump and the suction pump can balance the pressure of the peristaltic pump perfusion and the pressure of the suction pump suction, thereby guaranteeing the constant water pressure in the surgical environment in the body, avoiding the collapse of the human cavity, the loss of the surgical field and the occurrence of surgical accidents when too much water is sucked out, and avoiding the situation that the planing and cutting cause an incision, the water pressure is too large, the water is toxic due to the excessive pressure, and the human body is in danger of life.

[0017] When the suction force of the suction pump is increased and the water outlet pressure is greater than the water inlet pressure, the main machine automatically controls the peristaltic pump to increase the perfusion speed and the water injection amount; when the suction force of the suction pump is reduced and the water outlet pressure is less than the water inlet pressure, the main machine automatically controls the peristaltic pump to reduce the perfusion speed and the water injection amount, so as to guarantee the consistency of the water amount of the water inlet and the water outlet and the stability of the water amount and the water pressure of the surgical space.

[0018] The water amount required to be maintained during the operation can be preset through the operation interface before the operation, the water pressure can be directly adjusted through the operation interface if the water pressure is not suitable due to individual cases during the operation, the perfusion operation and the suction operation are realized on one machine, the back-and-forth operation of the ordinary irrigation equipment and the suction equipment is avoided, the operation time and the operation risk are reduced, and the operation process is optimized.

After the surgical field is opened, the pressure of the peristaltic pump and the suction pressure of the suction pump can be controlled to be the same through the pressure detection devices arranged on the peristaltic pump 5 and the suction pump, so as to ensure the constant water pressure in the surgical environment in the body, avoid the collapse of the human cavity caused by too much suction water, the loss of the surgical field, and the easy occurrence of surgical accidents. When the water inflow and pressure are too large, the planing cutting will cause the wound, and the excessive pressure will cause water poisoning, which will cause life-threatening to the human body.

[0025] When the water outflow pressure is greater than the water inflow pressure, the main machine 1 controls the peristaltic pump 5 to increase the water injection amount.

[0030] The arrangement of the trolley 9 and the universal wheels facilitates the carrying and moving of the main machine 1 and the negative pressure bottle 4, and the arrangement of the trolley 9 facilitates the dismounting and fixing of the negative pressure bottle 4, thereby providing convenience for the cleaning and replacement of parts of the subsequent machine.

[0031] The storage box 10 can prevent common spare parts, and if there is a damaged part during the operation process or before the machine is preheated, the damaged part can be quickly replaced.

[0032] The main machine 1 provides negative pressure, the negative pressure is communicated with the surgical instrument 2 through the negative pressure bottle 4, the lesion tissue cut off can be sucked out of the patient's body, the negative pressure bottle 4 can be one or a plurality of series, and a tissue collection bag can be further arranged in the first negative pressure bottle 4 communicated with the surgical instrument 2, the tissue collection bag can collect the lesion tissue, and subsequent processing is facilitated.

[0033] Working principle: the automatic constant pressure surgical power device in the planing cavity is controlled by the main machine to work the planing handle motor, drives the planing cutter to rotate and cut the lesion tissue, and sucks the lesion tissue out of the body through negative pressure suction. According to the operation requirement, the suction pump suction force is increased, when the water outlet pressure is increased and the pressure in the human cavity is not enough to collapse, the main machine automatically controls the peristaltic pump to increase the injection water pressure; the suction pump suction force is reduced, when the water outlet pressure is reduced and the pressure in the human cavity is too high, the main machine automatically controls the peristaltic pump to reduce the injection water amount, so that the water pressure difference between the inlet and outlet is constant, the pressure in the human cavity is stable, and the operation space is in a reasonable range. The utility model simultaneously realizes the functions of the surgical irrigation liquid injection and suction and the planing function in one machine, avoids the back and forth operation of the ordinary water injection equipment, the negative pressure water suction equipment and the planing equipment, reduces the operation risk of misoperation, and optimizes the operation process.
