Description

Technical Field

[0001] The present invention relates to the technical field of surgical aspirators, in particular to aspirators used in neurosurgery. Background Art

[0002] The suction device is used to remove bleeding, exudate, pus, and contents of chest organs during surgery to make the surgery clear and reduce the chance of contamination. The principle of the suction device is very simple, that is, to create a negative pressure state of its suction head through a certain method, so that the atmospheric pressure will squeeze the substances outside the suction head into the suction head, thereby achieving the "suction" effect.

[0003] The prior art (publication number: CN115137892A) discloses a neurosurgery suction device in the field of medical devices, including a main body, an ejection mechanism is arranged inside the main body, a fixed plate is fixedly connected inside the main body, a negative pressure mechanism is installed on the right side of the fixed plate, a fixed tube is slidably connected inside the ejection mechanism, a suction head is fixedly connected to one end of the fixed tube, a telescopic tube is snap-connected to the other end of the fixed tube, one end of the telescopic tube is fixedly connected to the left side of the fixed plate, an anti-slip sleeve is slidably connected to the outer surface of the main body, a control panel is arranged on the outer surface of the main body, the ejection mechanism includes a first screw rod, a first fixed rod, a first motor, a movable plate, a limit plate, a sleeve, a spring, a movable rod, a fixed block, and a limit rod. According to the present invention, the length of the fixed tube can be freely adjusted according to the needs of the user, and the fixed tube can be disassembled and fixed for future use, and the suction operation can be controlled, reducing the operating intensity of the staff.

[0004] Since the suction head of the prior art is directly exposed to the environment and the port of the suction head is always in a negative pressure state, if the suction head touches the nerve tissue of the wound, it will cause greater damage to the patient and affect the patient's postoperative recovery. For this reason, we proposed a suction device for neurosurgery to solve the above problems. Summary of the invention

[0005] The present invention is intended to provide a suction device for neurosurgery to solve the problem that the suction head touches the nerves of the wound and causes greater damage to the nerves.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a suction device for neurosurgery, including a suction body, characterized in that: it also includes a shell, the suction body is arranged in the shell, a positioning component is provided between the suction body and the shell, a plurality of slide grooves are opened through the shell, the positioning component includes a positioning ring, a locking ring, a connecting ring and a plurality of connecting rods, the plurality of connecting rods are respectively arranged in each slide groove, the locking ring is threadedly connected to the outer wall of the shell, the positioning ring is arranged at one end of each connecting rod close to the locking ring, the connecting ring is arranged at one end of each connecting rod away from the locking ring, and the suction body is located in the connecting ring.

[0007] The beneficial effects of this solution are as follows: by providing a slide groove in the outer shell, the connecting rod is slidably installed in the slide groove, so that the position of the connecting rod in the slide groove is adjusted by the connecting ring, and then the length of the positioning ring and the suction body is controlled, which is convenient for doctors to suction wounds of different depths. At the same time, the positioning ring is used to prevent the suction body from directly contacting the nerve tissue. Finally, when the doctor determines the extended length of the positioning ring, the locking ring is rotated to tighten the end of the outer shell to fix the connecting rod in the slide groove, thereby preventing the positioning ring from moving, which is beneficial to the staff to move the suction body.

[0008] Preferably, as an improvement, each connecting rod includes a first connecting rod, a second connecting rod and a spring sheet, the first connecting rod and the second connecting rod are both arranged in the slide groove, the positioning ring is arranged at one end of the first connecting rod close to the locking ring, the connecting ring is arranged at one end of the second connecting rod away from the locking ring, and the spring sheet is arranged between the first connecting rod and the second connecting rod.

[0009] The beneficial effect is: by connecting the spring sheet to the first connecting rod and the second connecting rod, when the doctor presses down the second connecting rod, the first connecting rod is fixed under the action of the locking ring, so that the spring sheet bends, and then the suction port of the suction body is closer to the positioning ring, so that the exudate from the wound is sucked more cleanly; when the spring sheet continues to bend and abuts against the inner wall of the slide groove, the suction body can no longer move downward, and at the same time, the suction port of the suction body is still higher than the positioning ring and does not contact the nerve tissue, thereby protecting the patient and preventing secondary injury during the operation.

[0010] Preferably, as an improvement, a through slot communicating with each slide slot is provided on the inner wall of the shell, each spring sheet is arranged in an arc shape, and the curved spring sheet can abut against the outer wall of the attraction body through the through slot.

[0011] The beneficial effect is as follows: by providing a through groove to connect the slide groove with the inner wall of the shell, the bent spring piece can be extended into the inner wall of the shell through the through groove and abut against the outer wall of the suction body. Since coagulation will appear during the operation and sink to the bottom of the effusion, the doctor needs to press down the connecting ring to make the suction port of the suction body closer to the bottom of the effusion, so as to suck away the coagulation. Since the air pressure of the existing suction body is constant, it is easy to cause the suction port of the suction body to be blocked by coagulation. In this solution, when the doctor presses down the connecting ring, the second connecting rod squeezes the spring piece, and the bent spring piece is The spring piece contacts and squeezes the outer wall of the suction body through the through groove, thereby reducing the cross-section of the inner wall of the suction body, increasing the flow rate of the gas inside the suction body, and increasing the negative pressure at the suction port of the suction body, prompting the solidified material to be sucked out of the body by the suction body. At the same time, since the suction body is usually connected to the negative pressure device, the suction body will be displaced in the extension direction during use, and the doctor needs to actively resist the displacement of the suction body, which affects the doctor's normal use. In this solution, the suction body is clamped by the spring piece to avoid the displacement of the suction body and increase the stability of the suction device.

[0012] Preferably, as an improvement, the positioning ring is configured to be in a truncated cone shape, and a through hole is provided in the middle thereof.

[0013] The beneficial effect is that by setting the positioning ring to be in a truncated cone shape, the accumulated liquid is gathered in the through hole in the middle of the positioning ring, and then the accumulated liquid is sucked out in cooperation with the suction body.

[0014] Preferably, as an improvement, a finger ring is provided on the outer wall of the connecting ring.

[0015] The beneficial effect is that the doctor inserts the thumb into the finger ring to control the connecting ring, and the remaining four fingers hold the outer shell, which increases the doctor's comfort in holding.

[0016] Preferably, as an improvement, one end of the housing close to the locking ring is configured to be conical and is made of elastic material.

[0017] The beneficial effect is that by setting the outer shell to be an elastic material, the first connecting rod can be directly fixed by the locking ring.

[0018] Preferably, as an improvement, a gooseneck ring is provided between the connecting ring and the outer shell, and the gooseneck ring is sleeved on the outer wall of each second connecting rod.

[0019] The beneficial effect is that the gooseneck tube is used to connect the connecting ring and the housing, so that the sliding of the second connecting rod is more stable.

[0020] Preferably, as an improvement, the suction port of the suction body is provided with saw teeth in a ring shape.

[0021] The beneficial effect is that the doctor repeatedly squeezes and releases the spring sheet to keep the negative pressure of the suction body changing, so that the coagulation material attached to the suction port of the suction body is constantly rubbed against the serrations at the suction port, thereby cutting the coagulation material, reducing the volume of the coagulation material, and further avoiding the suction port of the suction body from being blocked.

[0024] The following is further described in detail through specific implementation methods:

[0025] The reference numerals in the drawings of the specification include: attraction body 1, shell 2, slide groove 3, positioning ring 4, lock ring 5, connecting ring 6, first connecting rod 7, second connecting rod 8, spring piece 9, through groove 10, finger ring 11, gooseneck change 12.

[0026] Example

[0027] The embodiment is basically as shown in the attached Figure 1-2 As shown, Figure 1 The neurosurgery suction device shown in the figure comprises a suction body 1, a suction port of the suction body 1 is provided with saw teeth in an annular shape, and a shell 2, the suction body 1 is slidably mounted inside the shell 2, the lower end of the shell 2 is set to be conical, and is set to be an elastic material, a positioning component is provided between the suction body 1 and the shell 2, and the shell 2 is vertically penetrated with three slide grooves 3, and the positioning component comprises a positioning ring 4, a locking ring 5, a connecting ring 6 and three connecting rods, such as Figure 2As shown, three connecting rods are slidably installed in each slide groove 3, each connecting rod includes a first connecting rod 7, a second connecting rod 8 and a spring 9, the first connecting rod 7 and the second connecting rod 8 are slidably installed in the slide groove 3, the positioning ring 4 is fixedly installed at the lower end of the first connecting rod 7, the positioning ring 4 is set to be truncated, and a through hole is opened in the middle, the connecting ring 6 is fixedly installed at the upper end of the second connecting rod 8, and the suction body 1 is fixedly installed in the connecting ring 6, the spring 9 is fixedly installed between the first connecting rod 7 and the second connecting rod 8, and the housing 2 is fixedly installed in the connecting ring 6. The wall is provided with a through groove 10 connected with each slide groove 3, each spring piece 9 is arranged to be arc-shaped, and the protrusion of the spring piece 9 is close to the through groove 10, the bent spring piece 9 can abut against the outer wall of the attraction body 1 through the through groove 10, and the locking ring 5 is threadedly connected to the outer wall of the shell 2. Since the lower end of the shell 2 is conical and elastic, when the locking ring 5 rotates downward, the locking ring 5 will lock the lower end of the shell 2, thereby fixing the first connecting rod 7 in the slide groove 3 to prevent the first connecting rod 7 from being displaced in the slide groove 3, and a finger ring 11 is fixedly installed on the outer wall of the connecting ring 6.

[0028] A gooseneck ring is fixedly installed between the connecting ring 6 and the outer shell 2 , and the gooseneck ring is sleeved on the outer wall of each second connecting rod 8 .

[0029] Since coagulation may appear during the operation and sink to the bottom of the effusion, the doctor needs to press down the connecting ring 6 to make the suction port of the suction body 1 closer to the bottom of the effusion, so as to suck away the coagulation. Since the air pressure of the existing suction body 1 is constant, it is easy to cause the suction port of the suction body 1 to be blocked by coagulation. In this solution, when the doctor presses down the connecting ring 6, the second connecting rod 8 squeezes the spring sheet 9, and the bent spring sheet 9 abuts against and squeezes the outer wall of the suction body 1 through the through groove 10, thereby reducing the cross-section of the inner wall of the suction body 1, increasing the flow rate of the gas inside the suction body 1, and increasing the negative pressure of the suction port of the suction body 1, so as to cause the coagulation to be sucked out of the body by the suction body 1. At the same time, since the suction body 1 is usually connected to the negative pressure device, the suction body 1 will be displaced in the extension direction during use, and the doctor needs to actively resist the displacement of the suction body 1, which affects the doctor's normal use. In this solution, the suction body 1 is clamped by the bent spring sheet 9 to avoid the displacement of the suction body 1 and increase the stability of the aspirator.

[0030] The specific implementation process is as follows:

[0031] When in use, the doctor holds the shell 2 with four fingers and inserts the thumb into the finger ring 11. At this time, the doctor controls the length of the positioning ring 4 and the suction body 1 extending out of the shell 2 by pressing down the finger ring 11. When the extended length meets the requirement, the first connecting rod 7 is fixed in the slide groove 3 by rotating the locking ring 5. When it is necessary to suction the effusion, the doctor first brings the positioning ring 4 into contact with the epidermis to avoid direct contact between the suction head of the suction body 1 and the nerve tissue. At this time, the finger ring 11 is pressed down again, and the suction port of the suction body 1 is brought closer to the positioning ring 4 by moving the connecting ring 6 downward, so that the exudate at the wound is sucked more cleanly. When the second connecting rod 8 is moved down, the suction port of the suction body 1 is brought closer to the positioning ring 4. During the operation, the spring piece 9 bends, and the bent spring piece 9 abuts against and squeezes the outer wall of the suction body 1 through the through groove 10, thereby reducing the cross-section of the inner wall of the suction body 1, increasing the flow rate of the gas inside the suction body 1, and increasing the negative pressure at the suction port of the suction body 1, prompting the coagulation to be sucked out of the body by the suction body 1; when the spring piece 9 continues to bend and completely abuts against the outer wall of the suction body 1, the suction body 1 can no longer move downward, and at this time the suction port of the suction body 1 is still located above the positioning ring 4 and is not in direct contact with the nerve tissue, thereby protecting the patient and preventing secondary injury during the operation.

[0032] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
