Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a brain cotton sheet negative pressure drainage clamp. Background Art

[0002] Brain cotton pads are essential items in neurosurgery and spinal surgery, and are very important for protecting the brain, spinal cord and nerve tissue. Ordinary brain cotton pads in the prior art are made of uncolored cotton fibers through conventional combing, mixing, laying and drafting. Brain cotton pads with development function are composed of polypropylene fibers and cotton fibers, and the polypropylene fibers contain barium sulfate.

[0003] At present, in almost all brain surgeries, it is necessary to place common brain cotton pads on the surgical site to absorb and clean the blood and other bloody fluids in the surgical field, make the surgical field clear, and facilitate the operation. Although the brain cotton pads in the prior art have certain blood-sucking and hemostatic functions, the blood-sucking capacity is limited. After being full of blood or body fluids, new brain cotton pads must be replaced in time, otherwise the newly-flowing blood from the wound will affect the surgical field of view. Sometimes, up to hundreds of brain cotton pads need to be used in brain surgery, which increases the doctor's operation time to a certain extent. Continuously replacing brain cotton pads will not only prolong the operation time, but also increase the risk of surgery, and repeatedly replacing brain cotton pads will also affect the doctor's operation quality and effect. In addition, the brain cotton pads commonly used now are white, and when performing surgery, they are easily dyed red by blood, are difficult to distinguish from the tissues around the wound, and are easily left in the wound.

[0004] Therefore, a solution to the above problems is needed. Utility Model Content

After being connected to the negative pressure suction device, the blood in the clamped brain cotton pad body and the adjacent surgical field can be sucked away in a timely and continuous manner through the suction channel, which is convenient for surgical operation and reduces the risk of surgery. In addition, the brain cotton pad does not need to be replaced during surgery, which greatly reduces the operation time. The brain cotton pad is easy to replace and can absorb the blood during surgery, which can keep the field of vision clear during surgery. The brain cotton pad is clamped by a clamping structure and can be replaced, so that it is compatible with brain cotton pads of any size and shape, and can be replaced at any time according to the needs during surgery.

[0026] In order to better understand the technical solution of the present utility model, the embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0027] It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 The figure shows the overall structure of the brain cotton pad negative pressure drainage clamp of the utility model.

[0029] like Figures 1 to 4 As shown, a brain cotton pad negative pressure drainage clamp includes a suction tube 1 and a clamping structure 2.

[0030] Among them, the clamping structure 2 can be used to clamp on the brain cotton piece 3, and a suction channel 21 is provided on the clamping structure 2. When the clamping structure 2 clamps on the brain cotton piece 3, the suction channel 21 is connected with the brain cotton piece 3; one end of the suction tube 1 is connected to the suction channel 21 of the clamping structure 2, and the other end can be used to connect to a negative pressure suction device (not shown). When the brain cotton piece 3 is in use, the negative pressure suction device can suck away blood during the operation through the suction tube 1 and the suction channel 21, so as to keep the field of vision clear and facilitate the operation.

[0031] refer to Figure 1 The clamping structure 2 is a plastic clamp with a large clamping surface. The brain cotton sheet 3 can be clamped on the clamping structure 2, and the clamping structure is elastic and can keep the brain cotton sheet clamped. Specifically, the clamp is formed by connecting two clamping blocks 22, the two clamping blocks 22 are made of transparent plastic, and the two clamping blocks 22 are both roughly rectangular block structures. The two clamping blocks 22 are arranged opposite to each other and hinged together, and the two hinged clamping blocks 22 can rotate relative to each other, so that the angle between the two clamping blocks 22 can be changed to open or close the clamp for clamping the brain cotton sheet 3; an elastic member (not shown) is also arranged at the hinge of the two clamping blocks 22, and the elastic member can preferably be a torsion spring, so that the brain cotton sheet 3 can be automatically clamped between the two clamping blocks 22, and will not be automatically loosened, so as to keep clamping. Alternatively, in some other embodiments, the two clamping blocks 22 are an integral structure, the two clamping blocks 22 are arranged relative to each other, and one end of the two clamping blocks 22 is connected, and the other end can be used to clamp the brain cotton piece 3. There is no elastic part on the clamping mechanism, but the two clamping blocks 22 are made of plastic material and can be broken apart at one end, and can clamp the brain cotton piece 3 between the two clamping blocks 22 through their own elasticity.

[0032] Furthermore, the clamping block 22 is provided with clamping teeth 23, so that the clamping structure 2 can clamp more tightly when clamping the brain cotton sheet 3, and prevent the clamping structure 2 from falling off during the clamping process. Specifically, in this embodiment, the clamping teeth 23 are ribs arranged horizontally (in the width direction of the clamping block 22) on one of the clamping blocks 22 of the clamping structure 2. When clamping, the ribs are between the two clamping blocks 22, and can abut against the brain cotton sheet 3 clamped between the two clamping blocks 22. The ribs are pressed on the brain cotton sheet 3, so that the clamping structure 2 clamps the brain cotton sheet 3 more stably, and the brain cotton sheet 3 will not fall off easily.

[0033] Alternatively, in some other embodiments, the clamping structure 2 may also be provided with ribs as clamping teeth on both clamping blocks 22. Alternatively, in some other embodiments, the clamping teeth 23 may also be a plurality of teeth disposed transversely on one of the clamping blocks 22 of the clamping structure 2, and when the two clamping blocks 22 are connected, the teeth are located between the two clamping blocks 22, so that when the two clamping blocks 22 clamp the brain cotton sheet 3, the teeth can bite on the brain cotton sheet 3, so that the brain cotton sheet 3 is clamped by the clamping structure 2. Alternatively, in some other embodiments, the clamping teeth 23 may be provided on both clamping blocks 22.

[0034] In some embodiments, the suction channel 21 is arranged on the clamping structure 2 longitudinally (in the length direction of the clamping block 22), one end of the suction channel 21 is arranged at the clamping end of the clamping structure 2, and when the clamping structure 2 clamps the brain cotton sheet 3, it is connected to the brain cotton sheet 3, and the other end of the suction channel 21 is located at the other end of the clamping structure 2 opposite to the clamping end, so that this end is convenient for connecting the suction tube 1, will not affect the clamping structure 2 clamping the brain cotton sheet 3, and can prevent affecting the surgical operation. Specifically, in this embodiment, the clamping block 22 is a roughly rectangular block structure, one of the two clamping blocks 22 is provided with a suction channel 21 arranged along the length, one end outlet of the suction channel 21 is located at the end of the clamping block 22, and the other end outlet 24 is arranged on the side of the clamping block 22 facing the other clamping block 22, that is, the outlet 24 of the suction channel 21 can abut against the brain cotton sheet 3 clamped between the two clamping blocks 22, and is used to suck away the blood generated during the operation.

[0035] Further, refer to Figure 4 The outlet 24 of the liquid suction channel 21, which is arranged on the side of the clamping block 22 facing the other clamping block 22, is a substantially C-shaped structure.

[0036] In some embodiments, the straw 1 is a hose, one end of which is connected to the suction channel 21, and the other end can be connected to the negative pressure suction device. The negative pressure suction device and the clamping structure 2 are connected through the straw 1, so that the clamping structure 2 can absorb the blood during the operation when clamping the brain cotton pad 3, and keep the field of vision clear. Specifically, in this embodiment, the straw 1 is a transparent plastic hose, one end of which is glued to the clamping block 22 of the clamping structure 2 with the suction channel 21, and is connected to the suction channel 21 provided on the clamping block 22, and the other end is connected to the negative pressure suction device, and suction can be achieved by starting the negative pressure suction device. Alternatively, in some other embodiments, the straw 1 can also be an integrated structure with the clamping block 22 of the clamping structure 2, as long as it can be connected to the clamping block 22 and connected to the suction channel 21.

[0037] Furthermore, the suction tube 1 can be connected to the negative pressure suction device through a valve. Specifically, in this embodiment, the negative pressure suction device is a negative pressure suction bottle, and the suction tube 1 is connected to the negative pressure suction bottle through a three-way valve. When it is necessary to suck away blood to keep a clear field of vision during surgery, the three-way valve is adjusted to allow the negative pressure suction bottle to suck away blood.

[0038] When the utility model structure is used:

[0039] The clamping structure 2 is clamped on the tail end of the brain cotton piece 3 body, and the suction tube 1 is connected to the negative pressure suction device. During brain surgery, an ordinary brain cotton piece 3 is placed on the surgical site. When there is excessive bleeding during the operation, the three-way valve is opened, and the suction channel 21 can promptly and continuously absorb the blood soaked in the brain cotton piece 3 body and the surgical field of view, so that the negative pressure suction device can absorb and clean the blood and other bloody liquids in the surgical field to make the surgical field clear and facilitate surgical operations; and when the brain cotton piece 3 is seriously contaminated or damaged, the clamping structure 2 can be removed and the brain cotton piece 3 can be replaced. Brain cotton pieces 3 of different sizes can be replaced at any time during the operation.

[0040] The utility model discloses a brain cotton pad negative pressure drainage clamp, which is provided with a suction tube connected to a negative pressure suction device. After being connected to the negative pressure suction device, the blood in the clamped brain cotton pad body and the adjacent surgical field can be sucked away in a timely and continuous manner through the suction channel, which is convenient for surgical operation and reduces the risk of surgery. In addition, the brain cotton pad does not need to be replaced during surgery, which greatly reduces the surgical time. The brain cotton pad is easy to replace and can absorb the blood during surgery, so that the visual field during surgery can be kept clear. The brain cotton pad is clamped by a clamping structure and can be replaced, so that it is compatible with brain cotton pads of any size and shape, and can be replaced at any time according to the needs during surgery. Moreover, the novel brain cotton pad negative pressure drainage clamp has a reasonable design, a simple structure, is easy to prepare, has a good use effect, and has a broad prospect for clinical application.

[0041] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
