Description

Technical Field

[0001] The embodiments of this utility model relate to the field of blood suction device technology, specifically, to an anti-collision blood suction device. Background Technology

[0002] During surgery, a clear surgical field is crucial to ensure precise operation by the surgeon. Any interference with the surgical field can affect the surgeon's judgment of structures such as tissues, blood vessels, and nerves, thereby increasing surgical risks. During surgery, tissues may bleed due to surgical trauma. Additionally, if infection is present, pus may be produced. This blood and pus can cover the surgical area, obscuring the surgeon's vision and hindering the smooth progress of the procedure.

[0003] While the blood suction devices currently used in clinical practice can effectively remove blood and pus, ensuring a clear surgical field, in actual operation, even with utmost care, the tip of the device inevitably bumps into the tissue. Tissue is inherently fragile, and since blood suction devices are often made of metal, such impacts can easily damage the tissue, potentially causing additional bleeding, prolonging surgery time, and affecting the patient's recovery process.

[0004] Therefore, developing a collision-resistant blood suction device that can reduce the risk of tissue damage from impacts during use is of great significance for improving surgical quality and protecting patient health. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide an anti-collision blood suction device, which solves the technical problem in the related art that tissue parts are easily damaged by collision with the end of the blood suction device.

[0006] According to one aspect, at least one embodiment of the present invention provides an anti-collision blood suction device, including an operating handle and a silicone suction head. The operating handle has a negative pressure through hole arranged along its own extension direction. The tail of the operating handle is used to communicate with a negative pressure device. The silicone suction head is detachably disposed at the head of the operating handle and communicates with the operating handle. The silicone suction head is used to contact the tissue site to absorb the oozing blood. The silicone suction head is provided with a plurality of support rings arranged at intervals along its own extension direction. The support rings are used to expand the silicone suction head under the action of negative pressure to prevent the silicone suction head from collapsing and becoming blocked.

[0007] For example, in at least one embodiment of the present invention, an anti-collision blood suction device further includes:

[0008] The head of the silicone suction head is provided with a plurality of circumferentially arranged protrusions at intervals. The protrusions are used to contact the tissue site to prevent the head of the silicone suction head from adhering to the surface of the tissue site.

[0009] For example, in at least one embodiment of the present invention, an anti-collision blood suction device further includes:

[0010] The inner wall of the silicone suction head is provided with a plurality of annular grooves spaced apart along its own extension direction, and the plurality of support rings are embedded in the plurality of annular grooves one by one.

[0011] For example, in at least one embodiment of the present invention, an anti-collision blood suction device further includes:

[0012] A pressure-reducing hole is provided on the tail side wall of the operating handle.

[0013] For example, in at least one embodiment of the present invention, an anti-collision blood suction device further includes:

[0014] An adjustment plate is slidably provided on the outside of the operating handle. The adjustment plate is used to control the sealing area of ​​the pressure relief hole in order to adjust the negative pressure of the silicone suction head.

[0015] For example, in at least one embodiment of the present invention, an anti-collision blood suction device further includes:

[0016] A friction plate is provided on the side of the adjustment plate near the operating handle, and the friction plate is used to contact the outer wall of the operating handle to form a damping effect.

[0017] For example, in at least one embodiment of the present invention, an anti-collision blood suction device further includes:

[0018] A cut-off hole is provided on the peripheral wall of the operating handle. The cut-off hole is connected to the negative pressure through hole. A cut-off post is slidably disposed in the cut-off hole. The cut-off post can be inserted into the operating handle to cut off the negative pressure through hole.

[0019] For example, in at least one embodiment of the present invention, an anti-collision blood suction device further includes:

[0020] A spring is connected between the cut-off post and the inner wall of the cut-off hole. The spring is used to provide a force to move the cut-off post away from the negative pressure through hole, so that the cut-off post extends out of the cut-off hole.

[0021] For example, in at least one embodiment of the present invention, an anti-collision blood suction device further includes:

[0022] The silicone suction head is connected to the operating handle via a connector. One end of the connector is inserted into the silicone suction head, and the other end has a stepped insertion platform to adapt to the operating handle of different diameters.

[0023] For example, in at least one embodiment of the present invention, an anti-collision blood suction device further includes:

[0024] The connector has a force-applying ring on its outer periphery, the force-applying ring is located in the axial center of the connector, and the surface of the force-applying ring has anti-slip texture.

[0025] The beneficial effects of the embodiments of this utility model are as follows:

[0026] In this invention, compared to the metal end of a traditional blood suction device, the elasticity of the silicone suction head cushions the impact force when it collides with tissue, preventing hard impact on fragile tissue and reducing the possibility of tissue damage. The silicone suction head is detachably connected to the operating handle; after surgery, it can be removed for cleaning, disinfection, or replacement. During operation, the external negative pressure device transmits negative pressure to the silicone suction head through the negative pressure port on the operating handle. The support ring resists the negative pressure, preventing the silicone suction head from collapsing and ensuring the suction channel remains unobstructed, guaranteeing the normal suction function of the blood suction device. Simultaneously, because multiple support rings are spaced apart, the silicone portion between adjacent support rings can still bend and deform freely when the silicone suction head collides with tissue. This ensures the support rings do not affect the cushioning function of the silicone suction head, and the impact force is dispersed and buffered during the deformation of the silicone suction head, reducing the impact on the tissue.

[0039] like Figures 1-4 The diagram illustrates an anti-collision blood suction device according to one embodiment of the present invention, comprising an operating handle 1 and a silicone suction head 2. The operating handle 1 is the part used for hand-held operation of the blood suction device, and has a negative pressure through-hole 101 extending along its own extension direction, passing through both ends of the operating handle 1. The tail end of the operating handle 1 is used to connect to an external negative pressure device, and the negative pressure generated by the negative pressure device can be transmitted to the head of the operating handle 1 through the negative pressure through-hole 101. The silicone suction head 2 is detachably mounted on the head of the operating handle 1 and can be removed for cleaning, disinfection, or replacement after the procedure. The silicone suction head 2 is tubular, with its front end used to contact the tissue site to aspirate oozing blood or pus. The silicone suction head 2 is made of medical-grade silicone, which can reduce the impact intensity when in contact with tissue, reducing the risk of tissue damage. The inner wall of the silicone suction head 2 is provided with multiple support rings 3 spaced along its length, made of medical-grade plastic or metal.

[0040] Working Principle: Compared to the metal end of traditional blood suction devices, when the tip of the silicone suction head 2 collides with the tissue, the elasticity of the silicone cushions the impact force, avoiding a hard impact on fragile tissue and reducing the possibility of tissue damage. The silicone suction head 2 is detachably connected to the operating handle 1. After the surgery, the silicone suction head 2 can be removed for cleaning, disinfection, or replacement. When the blood suction device is working, the external negative pressure device transmits negative pressure to the silicone suction head 2 through the negative pressure through-hole 101 of the operating handle 1. The support ring 3 resists the negative pressure, preventing the silicone suction head 2 from being sucked down, ensuring that the suction channel is always unobstructed, and guaranteeing the normal suction function of the blood suction device. At the same time, since the multiple support rings 3 are spaced apart, when the tip of the silicone suction head 2 collides with the tissue, the silicone part between adjacent support rings 3 can still bend and deform freely, so that the support rings 3 do not affect the cushioning function of the silicone suction head 2. The impact force can be dispersed and buffered during the deformation of the silicone suction head 2, reducing the impact force on the tissue.

[0041] In some examples, such as Figure 2As shown, multiple protrusions 201 are circumferentially spaced along the edge of the end of the silicone suction head 2. Multiple annular grooves 202 are spaced along the length of the inner wall of the silicone suction head 2. After the support ring 3 is embedded in the annular grooves 202, it will not block the internal channel of the silicone suction head 2.

[0042] Working principle: The protrusion 201 at the end of the silicone suction head 2 creates a gap between the silicone suction head 2 and the tissue, preventing a tight fit and thus avoiding the silicone suction head 2 from adhering to the tissue due to negative pressure. This ensures that the silicone suction head 2 can effectively aspirate blood and pus, while avoiding unnecessary pulling and damage to the tissue. The annular groove 202 on the inner wall of the silicone suction head 2 provides an installation position for the support ring 3. After the support ring 3 is embedded in the annular groove 202, it is not easy to shift or shake. At the same time, the support ring 3 is basically flush with the inner wall of the silicone suction head 2 after being embedded, and will not obstruct the internal channel, ensuring that blood and pus can be smoothly aspirated by the silicone suction head 2.

[0043] In some examples, such as Figure 3 , 4 As shown, a pressure-reducing hole 102 is provided on the side wall of the tail of the operating handle 1. An adjusting plate 4 is slidably provided on the outer wall of the operating handle 1, and the sliding adjusting plate 4 can change the coverage area of ​​the pressure-reducing hole 102. A friction plate 5 is provided on the surface of the adjusting plate 4, covering the side of the adjusting plate 4 that contacts the outer wall of the operating handle 1.

[0044] Working Principle: The function of the decompression hole 102 is to release the negative pressure inside the operating handle 1 by communicating with the outside air, thereby reducing the negative pressure at the end of the silicone suction head 2. The negative pressure at the end of the silicone suction head 2 can be adjusted by changing the coverage area of ​​the decompression hole 102 through the sliding adjustment plate 4. Doctors can flexibly adjust the negative pressure according to the actual needs during surgery, such as the viscosity of blood or pus, to achieve the best suction effect while avoiding tissue damage due to excessive negative pressure. The friction plate 5 provides a certain degree of damping for the sliding of the adjustment plate 4. When the adjustment plate 4 is pushed to the appropriate position, the friction between the friction plate 5 and the outer wall of the operating handle 1 can prevent the adjustment plate 4 from shifting, ensuring that the adjustment plate 4 can remain in that position and maintain the set negative pressure.

[0045] In some examples, such as Figure 3 , 4As shown, a cutoff hole 103 is radially formed on the operating handle 1, and the cutoff hole 103 communicates with the negative pressure through hole 101. A cutoff post 6 is slidably disposed within the cutoff hole 103, and its diameter is larger than the diameter of the negative pressure through hole 101. The top end of the cutoff post 6 protrudes from the cutoff hole 103, facilitating finger pressure operation by the doctor. The cutoff hole 103 is a stepped hole, and a spring 7 is connected between the cutoff post 6 and the step on the inner wall of the cutoff hole 103, providing a force to the cutoff post 6 away from the negative pressure through hole 101, keeping the cutoff post 6 in the position where its top end protrudes from the cutoff hole 103.

[0046] Working principle: When the silicone suction head 2 accidentally adheres to tissue during surgery, the doctor can quickly press the portion of the cutting post 6 protruding from the cutting hole 103 to overcome the elastic force of the spring 7, causing the cutting post 6 to slide radially towards the negative pressure through hole 101 along the cutting hole 103. Since the diameter of the cutting post 6 is larger than that of the negative pressure through hole 101, when the cutting post 6 is inserted into the negative pressure through hole 101, it effectively blocks the transmission of negative pressure within the negative pressure through hole 101, thereby eliminating the negative pressure at the end of the silicone suction head 2 and releasing the adhesion to the tissue. When the doctor releases their finger, the spring 7 returns to its natural state, allowing the tip of the cutting post 6 to protrude again from the cutting hole 103, preparing for the next operation and restoring the procedure to normal use without affecting subsequent surgical procedures.

[0047] In some examples, such as Figure 2 As shown, connector 8 is used to connect silicone suction head 2 and operating handle 1. One end of connector 8 is inserted into silicone suction head 2, and the other end has a stepped insertion platform 801. The stepped insertion platform 801 has multiple circumferential surfaces of different diameters to accommodate operating handles 1 of various diameters. A force-applying ring 802 is provided in the middle of connector 8, and the surface of the force-applying ring 802 is designed with anti-slip texture.

[0048] Working principle: One end of connector 8 is inserted into silicone suction head 2, ensuring a tight seal between them. The other end, a stepped insertion platform 801, has multiple circumferential surfaces that adapt to different diameters, enabling universal connection between connector 8 and various operating handles 1, thus improving the compatibility of silicone suction head 2. Since silicone suction head 2 is made of soft material and not easily inserted or removed by direct force, a force-applying ring 802 is provided in the middle of connector 8. When connecting or disconnecting silicone suction head 2 from operating handle 1, the force-applying ring 802 can be held to insert or remove connector 8. The anti-slip texture on the surface of force-applying ring 802 enhances the friction between the finger and the ring, preventing operational errors caused by finger slippage.
