Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a cotton sheet cutter. Background Art

[0002] Brain cotton pads are very commonly used hemostatic materials in neurosurgery and play an important role. There are two common specifications of brain cotton pads, 3cm×2cm and 9cm×2cm. In order to facilitate the subsequent removal and counting from the surgical site, a 40cm long lead wire will be passed through and fixed at one end of the cotton pad in advance. In this way, when the brain cotton pad is used for intracranial hemostasis, the lead wire can be left outside the cranial cavity. After the operation, it is convenient to accurately count the brain cotton pads to ensure that there are no omissions, to ensure the safety of the patient and the smooth progress of the operation.

[0003] In actual clinical work, due to differences between surgeons and the variety of surgical types, the size of the required brain cotton pieces is not completely fixed, which often requires surgical nurses to perform targeted trimming based on the specific requirements of the surgeon. In some surgeries, the demand for brain cotton pieces is huge, and may even be as many as dozens or even hundreds of pieces. What is extremely critical is that the leads on the trimmed brain cotton pieces must be completely retained without any missing pieces, which requires the arrangement of special personnel to be responsible for the trimming work. In this way, not only is the overall workload huge, but it also consumes a lot of time and energy. Surgical nurses may need to concentrate for a long time to perform precise trimming operations, which is a big test of their physical strength and patience. At the same time, a lot of time spent on the processing of brain cotton pieces may also affect the overall efficiency and schedule of the operation to a certain extent. Summary of the invention

[0004] The present invention aims to provide a cotton sheet cutter to reduce the labor intensity of medical staff and improve the cutting efficiency of brain cotton sheets.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a cotton sheet cutter comprises a base, the base comprises a horizontal part and a vertical part connected in sequence, a detection buffer unit is provided on the horizontal part, a cutting frame is provided above the detection buffer unit, the cutting frame is used to cut the brain cotton sheet, the size of the cutting frame can be adjusted, one side of the cutting frame close to the vertical part is hinged on the vertical part, a through groove for placing a lead is provided on the vertical part, a pressing unit is provided in the through groove, the pressing unit is used to fix the lead in the through groove, the detection buffer unit is used to detect whether the connection between the lead and the brain cotton sheet is reliable, and can play a buffering role for the cutting frame.

[0006] The beneficial effects of this solution are as follows: when cutting the brain cotton piece, first rotate the cutting frame so that the cutting frame moves to the side away from the detection buffer unit, and after flipping the cutting frame, place the brain cotton piece on the detection buffer unit so that the end of the brain cotton piece close to the lead contacts the vertical part, and place the lead in the through groove, press the lead through the pressing unit, rotate the cutting frame so that the cutting frame moves to the side close to the detection buffer unit, and cut the brain cotton piece through the cutting frame. During the cutting process, the cutting frame applies a downward impact force to the detection buffer unit, causing the detection buffer unit to move downward, thereby causing pulling between the lead and the brain cotton piece. If the connection between the lead and the brain cotton piece is unreliable, the lead will be detached from the brain cotton piece. If the lead is detached from the brain cotton piece, it means that the quality of the brain cotton piece is unqualified.

[0007] If unqualified brain cotton pads are used to stop bleeding during surgery, there will be a hidden danger of brain cotton pads left in the surgical site. Once left in the surgical site, they will become foreign bodies, which may cause subsequent problems such as inflammatory reactions, infections, tissue adhesions, etc., affecting postoperative recovery and patient health. If the brain cotton pads are left in the patient's body and are not discovered in time, subsequent searches may be difficult, and further measures such as imaging examinations may be needed to locate and remove them, increasing the patient's pain and medical costs, causing great psychological trauma and mental pressure to the patient, and even causing mental illness. In some serious cases, it may directly endanger the patient's life. It is also easy to cause conflicts between doctors and patients and medical disputes, and have an adverse impact on hospitals and medical staff.

[0008] Due to the setting of the cutting frame and the detection buffer unit, the technical solution can cut multiple brain cotton pieces at a time when cutting brain cotton pieces, with high cutting efficiency, which can reduce the labor intensity of medical staff and has low technical requirements for medical staff. It can also make the sizes of the cut brain cotton pieces more consistent, and at the same time, it will not affect the overall efficiency and schedule of the operation.

[0009] Since the size of the cutting frame of the technical solution can be adjusted, the brain cotton piece of appropriate size can be cut according to actual needs.

[0010] Due to the provision of the detection buffer unit, the technical solution can detect whether the connection between the brain cotton piece and the lead wire is reliable, detect unqualified brain cotton pieces, and at the same time, can also play a buffering role.

[0011] Furthermore, the detection buffer unit includes a cutting plate, a side of the cutting plate close to the vertical part is in contact with the vertical part, a plurality of guide rods are fixedly connected to the bottom of the cutting plate, a plurality of guide sleeves are fixedly connected to the upper side of the horizontal part, the guide rods correspond to the guide sleeves one by one, and the guide rods are slidably arranged in the guide sleeves, a plurality of elastic parts are arranged between the cutting plate and the horizontal part, one end of the elastic part is fixedly connected to the horizontal part, and the other end of the elastic part is in contact with the bottom of the cutting plate.

[0012] The beneficial effects of this solution are as follows: in this technical solution, since the guide rod is slidably arranged in the guide sleeve, and a plurality of elastic parts are arranged between the cutting plate and the horizontal part, during the process of cutting the brain cotton piece, the cutting frame will exert a downward impact force on the cutting plate, causing the cutting plate to move downward. At this time, a pull is generated between the lead wire and the brain cotton piece. If the quality of the brain cotton piece is unqualified, the lead wire will be pulled down. Therefore, this technical solution can detect whether the brain cotton piece is qualified. At the same time, due to the setting of the elastic part, it can play a buffering role during the cutting process, effectively buffer the impact force when the cutting frame falls, reduce damage to the cutting plate and the cutting frame itself, and extend its service life. It can also avoid the cutting frame from directly and strongly hitting the cutting plate, reducing the possibility of damage to the cutting plate and cut marks, ensuring the flatness and precision of the cutting plate, and making the cutting process smoother, which helps to ensure the accuracy and consistency of the cutting, improve the cutting quality of the brain cotton piece, make the edge of the brain cotton piece more neat, avoid the uneven edges from causing unnecessary damage to the tissue during use, and prevent the loose fiber burrs from being left in the surgical site and causing adverse consequences.

[0013] In the technical solution, since the guide rod is slidably arranged in the guide sleeve, the elastic member contacts the bottom of the cutting plate, thus facilitating the replacement of the cutting plate.

[0014] Furthermore, the cutting frame is a frame structure surrounded by a movable plate, cutting knife No. 1, cutting knife No. 2 and cutting knife No. 3 in sequence, the side of the movable plate away from the horizontal part is hinged on the vertical part, one end of the cutting knife No. 1 close to the movable plate is horizontally slidably arranged on the side of the movable plate close to the horizontal part, one end of the cutting knife No. 2 close to the cutting knife No. 1 is horizontally slidably arranged on the side of the cutting knife No. 1 close to the cutting knife No. 3, one end of the cutting knife No. 3 close to the cutting knife No. 2 is horizontally slidably arranged on the side of the cutting knife No. 2 close to the movable plate, one end of the movable plate close to the cutting knife No. 3 is horizontally slidably arranged on the side of the cutting knife No. 3 close to the cutting knife No. 1, the upper side surface of the vertical part is provided with a through hole running through its bottom, and the cutting knife No. 3 can slide horizontally into the through hole.

[0015] The beneficial effect of this solution is as follows: in this technical solution, since the end of the No. 1 cutting knife close to the movable plate is horizontally slidably arranged on the side of the movable plate close to the horizontal part, and the end of the No. 2 cutting knife close to the No. 1 cutting knife is horizontally slidably arranged on the side of the No. 1 cutting knife close to the No. 3 cutting knife, the No. 1 cutting knife can be slid toward or away from the side of the No. 3 cutting knife to adjust the width of the cutting frame.

[0016] In the present technical solution, the end of the No. 3 cutting knife close to the No. 2 cutting knife is horizontally slidably arranged on the side of the No. 2 cutting knife close to the movable plate, and the end of the movable plate close to the No. 3 cutting knife is horizontally slidably arranged on the side of the No. 3 cutting knife close to the No. 1 cutting knife. A through hole is provided on the upper side surface of the vertical portion, and the No. 3 cutting knife can pass through the through hole horizontally. Therefore, by sliding the No. 2 cutting knife to the side close to or away from the movable plate, the length of the cutting frame can be adjusted.

[0017] Due to the provision of the through hole, the technical solution facilitates the No. 3 cutting knife to move to the side close to the movable plate, while ensuring the normal rotation of the cutting frame.

[0018] Furthermore, a scale is provided on one side of the movable plate close to the horizontal part, and the zero scale point is located at one end of the movable plate close to the No. 3 cutting knife. A scale is also provided on one side of the No. 1 cutting knife close to the No. 3 cutting knife, and the zero scale point is located at one end of the No. 1 cutting knife close to the movable plate.

[0019] The beneficial effects of this solution are as follows: this technical solution sets scales on the movable plate and the No. 1 cutting knife, allowing the operator to perform accurate positioning and measurement, ensuring that the size of the cut brain cotton piece meets the requirements and reducing errors, and the operator can quickly and intuitively adjust the size of the cutting frame according to the scale without the need for additional measuring tools, thereby improving work efficiency; at the same time, it also helps to achieve standardization of cutting operations, and different personnel can perform consistent operations based on the scale, with low technical requirements for the operator.

[0020] The technical solution sets the zero scale point on the movable plate at one end of the movable plate close to the third cutting knife, and sets the zero scale point on the first cutting knife at one end of the first cutting knife close to the movable plate, so that the operator can adjust the size of the cutting frame easily.

[0021] Furthermore, a positioning unit is provided on one side of the movable plate close to the horizontal portion, the positioning unit is located between the through hole and the through groove, and the positioning unit is used to press the brain cotton piece on the cutting plate.

[0023] Furthermore, the positioning unit comprises a connecting bar, the connecting bar is fixedly connected to the movable plate, the bottom of the free end of the connecting bar is fixedly connected to an elastic member, and the free end of the elastic member is fixedly connected to a pressing plate.

[0024] The beneficial effects of this solution are as follows: since the connecting strip is fixedly connected to the movable plate, the bottom of the free end of the connecting strip is fixedly connected to an elastic member, and the free end of the elastic member is fixedly connected to a pressing plate, during the rotation of the cutting frame, the pressing plate can be driven to rotate synchronously, so that the pressing plate can continuously press the brain cotton piece to prevent the brain cotton piece from moving during the cutting process, thereby improving the stability of the brain cotton piece; due to the setting of the elastic member, the elastic member is elastic and can provide appropriate compression force when pressing the brain cotton piece, while allowing necessary deformation to adapt to subtle changes in the brain cotton piece, further ensuring the stability of the position of the brain cotton piece during cutting, reducing the cutting irregularity caused by the movement of the brain cotton piece, and improving the safety of the operation.

[0025] Furthermore, the pressing plate and the elastic member are coaxially arranged.

[0026] The beneficial effect of this solution is: since the pressing plate and the elastic member are coaxially arranged in this technical solution, the pressing plate is subjected to more uniform force, and can provide stable pressure for the brain cotton piece when the cutting frame rotates, so that the brain cotton piece remains fixed.

[0027] Furthermore, a plurality of limiting units are provided on the top of the cutting frame, and a plurality of limiting units are provided on the top of the cutting frame, and the limiting units can limit the cutting frame in the horizontal and vertical directions.

There is a gap between the fixed shaft 23 and the heightening plate and the limit strip 21, which can ensure the normal rotation of the rotating rod 24.

[0047] The specific implementation process is as follows:

[0048] When cutting the brain cotton piece, hold the handle 14, flip the cutting frame 28 upwards, and then place the brain cotton piece flat on the cutting board 3 so that the left side of the brain cotton piece contacts the right side surface of the vertical part 2, and place the lead wire in the through groove 15, slide the pressing plate 16 vertically in the through groove 15, and manually apply pressure to press the lead wire through the pressing plate 16 to achieve the initial positioning of the brain cotton piece; then adjust the size of the cutting frame 28. When it is necessary to adjust the width of the cutting frame 28, slide the No. 1 cutting knife 8 so that the left end of the No. 1 cutting knife 8 slides along the right side surface of the movable plate 7, and the right end of the No. 3 cutting knife 9 slides on the left side surface of the No. 2 cutting knife 27 to achieve the width adjustment of the cutting frame 28; when it is necessary to adjust the length of the cutting frame 28, slide the No. 2 cutting knife 27 so that the rear end of the No. 2 cutting knife 27 slides along the front side surface of the No. 1 cutting knife 8, and the front end of the movable plate 7 slides on the left side surface of the No. 3 cutting knife The rear side of the knife 9 slides to adjust the length of the cutting frame 28; after the size of the cutting frame 28 is adjusted, the cutting frame 28 is limited horizontally and vertically by the limiting unit, and then the handle 14 is held to flip the cutting frame 28 downward, and the brain cotton sheet on the cutting plate 3 is cut by the cutting frame 28. During the cutting process, the pressing plate 19 is in contact with the brain cotton sheet, and as the cutting frame 28 rotates, the pressing plate 19 is driven to rotate synchronously, so that the pressing plate 19 can continuously press the brain cotton sheet to prevent the brain cotton sheet from moving during the cutting process, thereby improving the stability of the brain cotton sheet; since the elastic member 18 is elastic, it can provide appropriate compression force when pressing the brain cotton sheet, while allowing necessary deformation to adapt to subtle changes in the brain cotton sheet, further ensuring the stability of the position of the brain cotton sheet during cutting, reducing the cutting irregularity caused by the movement of the brain cotton sheet, and improving the safety of the operation.

[0049] During the cutting process, the cutting frame 28 will apply a downward impact force to the cutting plate 3, causing the cutting plate 3 to move downward, thereby causing a pull between the lead and the brain cotton piece. If the connection between the lead and the brain cotton piece is unreliable, the lead will be separated from the brain cotton piece. If the lead is separated from the brain cotton piece, it means that the quality of the brain cotton piece is unqualified. By testing the quality of the brain cotton piece, even if the lead is not located in the middle of the brain cotton piece after cutting, there will be no problem of the lead falling off during use; at the same time, the elastic member 6 can also play a buffering role, effectively buffering the impact of the cutting frame 28 when it falls. The impact force can reduce the damage to the cutting board 3 and the cutting frame 28 itself, extend their service life, and prevent the cutting frame 28 from directly and forcefully hitting the cutting board 3, reduce the possibility of damage to the cutting board 3 and cut marks, ensure the flatness and precision of the cutting board 3, and make the cutting process smoother, which helps to ensure the accuracy and consistency of cutting, improve the cutting quality of the brain cotton piece, make the edge of the brain cotton piece more neat, avoid the uneven edges from causing unnecessary damage to the tissue during use, and prevent the loose fiber burrs from being left in the surgical site and causing adverse consequences.
