Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to an ophthalmic surgery blood wiping device. BACKGROUND

[0002] In ophthalmic surgery, cotton fibers (cotton swabs) are a commonly used tool, mainly used for wiping the bleeding or secretions in the surgical area to keep the surgical field clear. However, the use of traditional cotton fibers in ophthalmic surgery also has some problems: first, the liquid absorption capacity of cotton fibers is limited, and they need to be frequently replaced after each use, resulting in a large number of cotton fibers being discarded, increasing the consumption of surgical materials, and frequent replacement of cotton fibers will disrupt the surgical process, prolong the operation time, and increase the patient's surgical risk and discomfort; second, cotton fibers are prone to shed fibers or debris during use, and these residues may enter the surgical wound, causing foreign body reactions, and the residual fibers may also irritate the ocular tissues, causing inflammatory reactions, affecting wound healing, and even causing infection; third, the irregular shape and rough surface of cotton fibers can easily interfere with the clarity of the surgical field under a microscope, causing the doctor to misjudge during operation, increasing the risk of surgery.

[0003] Therefore, in order to reduce the risk of surgery, a dedicated ophthalmic surgery blood wiping device is needed. SUMMARY

[0027] Figure 2 This is a cross-sectional view of the suction head of this utility model. Detailed Implementation

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown: This embodiment provides an ophthalmic surgical blood wiping device, including a suction head 100, a connecting tube 200 and a deformable pressure bladder 300 connected in sequence.

[0031] The suction head 100 has a first cavity 101 inside, and its surface has a plurality of suction holes 102 communicating with the first cavity 101; specifically, the suction head 100 is located at the left end of the device (left and right are respectively). Figure 1 (The orientation shown is the same below). The interior is provided with a first cavity 101, and the surface is evenly distributed with a number of suction holes 102. These suction holes 102 are used to absorb blood or fluid from the surgical area.

[0032] The suction head 100 can be a semi-elliptical spherical shape with a size of about 4x6 mm, made of silica gel material; the silica gel elasticity is used to tightly sleeve the left end of the connecting pipe 200. The lower side of the suction head 100 is provided with a flat part 103, and the liquid suction holes 102 can be uniformly distributed on the flat part 103, which can ensure that the contact between the suction head 100 and the surgical area is more stable and close, and the uniform distribution of the liquid suction holes 102 can efficiently absorb the bleeding or liquid, avoiding excessive or weak local suction.

[0033] The front, upper, left and right sides of the suction head 100 can be smooth arc structures; the smooth arc structure can avoid scratching or damaging the surrounding tissue when the suction head 100 moves in the surgical area, especially in ophthalmic surgery, the eye tissue is relatively fragile, this design can significantly reduce the potential damage to the eye tissue; the arc structure makes the movement of the suction head 100 in the surgical area more smooth, which can better adapt to the operation requirements of different angles and positions, especially in microsurgery, this flexibility is crucial to improve the operation precision; the smooth arc design reduces the friction and interference between the suction head 100 and the surgical area, which can better maintain the clarity of the surgical field, avoiding the occlusion of the visual field caused by the irregular shape of the suction head 100.

[0034] The connecting pipe 200 is provided with a second cavity 201; the connecting pipe 200 is used for the transmission of liquid, which facilitates the movement of the suction head 100 to the surgical site; the left and right ends of the connecting pipe 200 are fixedly sleeved on the suction head 100 and the connecting end of the deformation pressure bag 300, respectively.

[0035] As a preferred, the connecting pipe 200 is an expanding pipe structure with gradually increasing pipe diameter from left to right, which can effectively reduce the resistance of liquid in the transmission process; during the negative pressure suction process, when the liquid enters the connecting pipe 200 from the suction head 100, the gradually increasing pipe diameter can better adapt to the change of liquid flow, avoiding the loss of negative pressure caused by too small pipe diameter; at the same time, since the pipe diameter of the connecting pipe 200 gradually increases, the liquid can flow more smoothly to the deformation pressure bag 300 in the transmission process, reducing the possibility of liquid backflow, preventing the recontamination of the surgical area or interfering with the surgical field. For example, the connecting pipe 200 can be 3 cm long, with a diameter of 3 mm at the left end and a diameter of 5 mm at the right end, made of hard plastic, and the diameter of the second cavity 201 thereof can be 2 mm.

[0036] The third cavity 301 is provided in the deformation compression bag 300, is made of elastic material, and can be made of silica gel material with high elasticity and tension. The deformation compression bag 300 can be deformed by extrusion (one hand of the user can achieve the extrusion) and restored after the extrusion disappears, so that the third cavity 301 can be synchronously deformed or restored. The first cavity 101, the second cavity 201 and the third cavity 301 are sequentially connected. The deformation compression bag 300 is an oval sphere with a length of 3 cm and a diameter of 1.5 cm.

[0037] Before use, it is checked whether the suction head 100, the connecting pipe 200 and the press bag are firmly connected, the sealing property of the device is ensured, the device is strictly sterilized to ensure that it meets the sterile requirements of the operation, the user holds the device, pre-presses the press bag to make it shrink, at this time, the air in the third cavity 301 is discharged, and a negative pressure is formed in the device. The liquid suction hole 102 of the suction head 100 is aligned with the bleeding or liquid part of the operation area, the suction head 100 should be in close contact with the part to be wiped, to ensure that the liquid suction hole 102 can effectively absorb the liquid. After the suction head 100 contacts the bleeding part, the pre-pressed press bag is loosened, and due to the elastic restoring effect of the press bag, the third cavity 301 rapidly expands, and a negative pressure is formed inside. The negative pressure is transmitted to the first cavity 101 of the suction head 100 through the connecting pipe 200, so that the liquid suction hole 102 generates suction force to suck the bleeding or liquid. The sucked liquid sequentially passes through the first cavity 101 of the suction head 100, the second cavity 201 of the connecting pipe 200 and finally enters the third cavity 301 of the press bag, and the liquid is temporarily stored in the third cavity 301. If further liquid suction is required, the press bag can be repeatedly pressed and loosened to make the device continuously generate negative pressure and absorb more liquid. When a certain amount of liquid accumulates in the third cavity 301, the press bag can be pressed again to discharge the liquid. The discharged liquid can be discharged from the device through the liquid outlet or be treated by other means. After the liquid is discharged, the device can continue to be used for liquid suction until the bleeding or liquid in the operation area is cleaned. After the operation is completed, the residual liquid in the device is cleaned to ensure the cleanliness of the device. After the device is sterilized, it is properly stored for subsequent use.

[0038] Embodiment two

[0039] The ophthalmic surgery blood wiping device provided in the embodiment can be further improved on the basis of the structure and principle shown in the embodiment one, and therefore the same structure and principle between the two are not described here.

[0040] In this embodiment, the connection between the third cavity 301 and the second cavity 201 is provided with a first one-way communication component 401, which blocks the communication between the third cavity 301 and the second cavity 201 during the contraction of the third cavity 301 and opens the communication between the third cavity 301 and the second cavity 201 during the restoration of the third cavity 301; the connection between the third cavity 301 and the outside is provided with a second one-way communication component 402, which opens the communication between the third cavity 301 and the outside during the contraction of the third cavity 301 and blocks the communication between the third cavity 301 and the outside during the restoration of the third cavity 301.

[0041] The synergistic effect of the one-way communication components ensures the stable generation and release of negative pressure, reducing the surgical interference caused by negative pressure fluctuations; the first one-way communication component 401 blocks the passage when the third cavity 301 contracts, preventing liquid backflow and ensuring one-way liquid flow; it opens the passage when the third cavity 301 restores, allowing liquid to enter; the second one-way communication component 402 opens the passage when the third cavity 301 contracts, allowing air to escape and quickly establishing negative pressure, and closes the passage when it restores, preventing air from entering; this structure can effectively control the generation and release of negative pressure, ensuring the stability and accuracy of negative pressure; through the control of one-way communication components, the generation and release of negative pressure are more orderly, avoiding the negative pressure fluctuation problem that may occur in traditional devices, thereby improving the stability during the operation process, realizing the continuous action of the device, and improving the use efficiency and effect; the one-way communication components can ensure the stability of negative pressure, reduce the surgical field interference caused by negative pressure fluctuations, improve the accuracy of the operation, control the intake and discharge of liquid, reduce the residue of liquid in the device, and avoid secondary pollution of the surgical area caused by liquid backflow; at the same time, the one-way communication components also reduce the possibility of liquid backflow and air entry, thereby reducing the risk of infection during the operation process.

[0042] In this embodiment, the first one-way communication component 401 is a silicone film structure (preferably a circular film) and is positioned in the third cavity 301 by the ligament on both sides (which can be the upper and lower sides); the second one-way communication component 402 is a silicone film structure and is positioned outside the third cavity 301 by the ligament 500 on both sides. Specifically, the left and right ends of the deformation compression sac 300 are respectively provided with a first connector 302 for connecting with the connecting tube 200 and a second connector 303 for communicating with the outside, the first one-way communication component 401 is arranged on the side of the first connector 302 located in the third cavity 301, and the second one-way communication component 402 is arranged on the side of the second connector 303 located outside the third cavity 301.

[0043] The silicon film has good biocompatibility, does not irritate or produce toxic reaction to the eye tissue, has flexibility and elasticity, and can keep stable performance under different pressure states, thereby ensuring reliable work of the one-way communication member; the ligament 500 has elasticity, and the one-way communication member is fixed in and out of the third cavity 301 through the ligament 500, so that the one-way communication member can keep a stable position during the operation, and displacement of the communication member caused by movement or vibration of the device is avoided.

[0044] The first one-way communication member 401 and the second one-way communication member 402 can only be opened in one direction; when the deformation pressure bag 300 is deformed by force, the third cavity 301 is reduced, and at this time, the third cavity 301 generates pressure due to the reduction, which is transmitted to the first one-way communication member 401 on one hand, and promotes the first one-way communication member 401 to be tightly attached to the inner wall of the first connector 302 (the side close to the third cavity 301), and is transmitted to the second one-way communication member 402 on the other hand, and promotes the second one-way communication member 402 to be displaced outward, so that a gap is generated between the second one-way communication member 402 and the second connector 303, and the liquid or gas in the third cavity 301 is discharged through the gap;

[0045] When the extrusion on the deformation pressure bag 300 is removed, the deformation pressure bag 300 returns to the original shape due to its elasticity; at this time, the volume of the third cavity 301 is increased, and negative pressure is generated; the negative pressure promotes the first one-way communication member 401 to move to the third cavity 301 on one hand, and causes a gap between the first one-way communication member 401 and the first connector 302, and promotes the second one-way communication member 402 to be tightly attached to the outer wall of the second connector 303 (the side away from the third cavity 301) on the other hand, thereby preventing external air from entering.

[0046] The above is only an embodiment of the present application, and the well-known specific structure and characteristics and other common knowledge in the scheme are not described in detail. It should be pointed out that, for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be regarded as the protection range of the present application, and these will not affect the effect and practicality of the present application. The protection range claimed in the present application should be subject to the content of the claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
