Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to a splash-proof baffle for orthopedic surgery. Background Art

[0002] In orthopedic surgery, especially knee and hip replacement surgeries, electric saws are usually used to cut bones and joint bones at the surgical site. Bone chips and blood generated during the cutting process will splash around, which not only affects the safety and hygiene of medical staff and increases the risk of occupational exposure for medical staff, but also may cause the splashed bone chips to contact the non-sterile area and bounce back to the sterile area, thereby increasing the risk of surgical infection. In order to solve the problem of bone chips and blood splashing, splash shields are usually used in orthopedic surgery to achieve protection purposes.

[0003] The splash shield of the prior art is an integrally formed component, including a handle and a transparent shield body, and the overall structure is similar to that of a cattail leaf fan. The above-mentioned splash shield has the following problems during actual use: (1) During orthopedic surgery, multiple medical staff are usually required to operate multiple surgical instruments at the same time. The integrally formed splash shield is easy to interfere with other surgical instruments, and the applicable surgical operation scenarios are relatively limited; (2) After repeated use, the transparent shield body is easily scratched by flying bone chips, affecting the clarity of the surgical field of view. At this time, the entire splash shield needs to be replaced to ensure a clear surgical field of view, resulting in a high cost for replacing surgical instruments. Utility Model Content

[0004] The utility model is intended to provide a splash shield for orthopedic surgery, so as to solve the technical problems that the splash shield in the prior art is easy to interfere with other surgical instruments and the applicable surgical operation scenes are relatively limited.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A splash shield for orthopedic surgery comprises a transparent shield body and a handle connected to the bottom of the shield body, wherein the shield body is an arc-shaped shield body and is tilted inward relative to the handle; the shield body comprises a shielding portion and a connecting portion, wherein the connecting portion is located between the shielding portion and the handle, and the width of the connecting portion gradually decreases from top to bottom.

[0007] The principle and beneficial effects of this program:

[0008] In actual application, the splash shield is disinfected in advance. When an electric saw is used to cut bones and joint bones in the surgical area during orthopedic surgery, the medical staff holds the splash shield by the handle and moves the shield body above the surgical area to shield the surgical area to prevent bone chips and blood generated during the cutting process from splashing around. This not only ensures the safety and hygiene of the medical staff and reduces or even avoids the risk of occupational exposure of the medical staff, but also prevents the splashed bone chips from contacting the non-sterile area. Even if the bone chips are bounced back to the sterile area after contacting the shield body, the risk of surgical infection can be reduced or even avoided.

[0009] 1. In this scheme, the baffle body is set as an arc-shaped baffle body, and the baffle body can be used to semi-enclose the surgical site, which can effectively improve the shielding effect of the baffle body on flying bone chips and blood, thereby further reducing the risk of occupational exposure of medical staff and the risk of surgical infection of patients.

[0010] 2. In this solution, the baffle body is tilted inward relative to the handle, that is, the entire splash baffle is bent. Since most surgical instruments are arranged in a straight line, when the splash baffle is used simultaneously with other surgical instruments, interference between the splash baffle and other surgical instruments can be avoided to a certain extent, thereby increasing the surgical operation scenarios of the splash baffle.

[0011] 3. The baffle body in this scheme includes a shielding part and a connecting part. The width of the connecting part between the shielding part and the handle gradually decreases from top to bottom. This can prevent the width of the connection between the baffle body and the handle from being too wide, thereby preventing this part from interfering with the use of other surgical instruments, and ensure that the connection between the baffle body and the handle still has a certain shielding effect, preventing bone chips and blood from splashing onto the face of medical staff from there, thereby ensuring the safety and hygiene of medical staff.

[0012] Preferably, as an improvement, the shielding portion is hinged to the handle to achieve adjustment of the inclination angle of the baffle body relative to the handle.

[0013] Beneficial effect: In this solution, the shielding part is hinged to the handle so that the shielding part can rotate relative to the handle, that is, the baffle body can rotate relative to the handle to achieve adjustment of the inclination angle of the baffle body relative to the handle. In this way, the inclination angle of the baffle body relative to the handle can be adjusted to avoid interference between the entire splash shield and other surgical instruments, thereby further increasing the surgical operation scenarios applicable to the splash shield and improving the practicality of the splash shield.

[0014] Preferably, as an improvement, a connecting seat is provided at the bottom of the shielding portion, and the connecting seat and the handle are connected via a ball hinge.

[0015] Beneficial effect: This solution realizes the connection between the connecting seat and the handle through a ball hinge, that is, the connection between the baffle body and the handle is realized through a ball hinge. Compared with the general hinge connection, the rotational freedom of the baffle body relative to the handle can be increased, so that the baffle body can rotate in multiple directions relative to the handle, which is more conducive to avoiding interference between the splash baffle and other surgical instruments, further increasing the surgical operation scenarios applicable to the splash baffle, and improving the practicality of the splash baffle.

[0016] Preferably, as an improvement, a connecting piece is provided between the shielding portion and the connecting seat, and the connecting piece is used to realize a detachable connection between the baffle body and the handle.

[0017] Beneficial effects: In this solution, a connecting piece is provided between the shielding part and the connecting seat, and the shielding part is detachably connected to the handle through the connecting piece, so that the detachable connection between the baffle body and the handle can be realized. When the transparent baffle body is scratched by splashed bone chips during long-term use, in order to ensure the clarity of the surgical field, the baffle body can be disassembled through the connecting piece to achieve the separate replacement of the baffle body. Compared with the existing technology of replacing the splash baffle as a whole, the replacement cost of surgical instruments can be effectively reduced. In addition, the baffle body can be used as a disposable consumable item and replaced after each operation, while the handle can be recycled, cleaned, disinfected and reused to maximize the clarity of the surgical field.

[0018] Preferably, as an improvement, the connecting member includes a connecting rod arranged at the bottom of the shielding portion and a connecting cylinder arranged at the top of the connecting seat, the connecting rod is slidably connected in the connecting cylinder, and a limit member is provided between the connecting rod and the connecting cylinder.

[0019] Beneficial effects: This solution realizes the detachable connection between the baffle body and the handle by sliding cooperation between the connecting rod set at the bottom of the shielding part and the connecting tube set at the top of the connecting seat. The structure is simple and easy to operate. And the limiting piece set between the connecting rod and the connecting tube realizes the limit of the connecting rod after being inserted into the connecting tube, ensuring the position stability of the connecting rod relative to the connecting tube during use, thereby ensuring the position stability of the baffle body relative to the handle during use, and then effectively shielding the splashed bone chips and blood, ensuring the safety of medical staff and patients during surgery.

[0020] Preferably, as an improvement, the limiting member includes a limiting groove, a limiting hole and a limiting ball, the limiting groove is circumferentially arranged on the side wall of the connecting rod, the limiting hole is radially arranged on the connecting cylinder, and the limiting hole is relative to the limiting groove, the limiting ball is movably arranged in the limiting hole, and the diameter of the limiting ball is larger than the thickness of the limiting cylinder, and the limiting cylinder is provided with a tightening member for pressing the limiting ball in the limiting groove.

[0021] Beneficial effect: After the connecting rod is inserted into the connecting tube, the positions of the limiting groove and the limiting hole are relative, and the limiting ball movably arranged in the limiting hole is pressed against the limiting groove by the pressing member, so that the relative position of the connecting rod and the connecting tube can be fixed; when the baffle body needs to be replaced, the pressing effect of the pressing member on the limiting ball is cancelled, so that the limiting ball is no longer pressed against the limiting groove, and the connecting rod can be smoothly taken out of the connecting tube to replace the baffle body. This solution has a simple structure and is easy to operate, and after the limiting ball is pressed against the limiting groove by the pressing member, the position of the connecting rod relative to the connecting tube can be effectively limited.

[0022] Preferably, as an improvement, the clamping member includes a sliding sleeve, a clamping ring and a return spring, the sliding sleeve is slidably connected to the connecting seat, the position of the clamping ring corresponding to the limiting hole is arranged on the inner wall of the sliding sleeve, and the clamping ring is slidably connected to the connecting tube, the return spring is sleeved on the connecting tube, and the return spring is located between the clamping ring and the connecting seat.

[0023] Beneficial effect: This solution uses a tightening ring to tighten the limiting ball that is movably set in the limiting hole into the limiting groove, thereby realizing the position limitation of the connecting rod relative to the connecting tube; when the baffle body needs to be disassembled, the sliding sleeve is slid downward relative to the connecting seat, so that the tightening ring slides downward synchronously relative to the connecting tube until the tightening ring is no longer in contact with the limiting ball. At this time, the limiting ball can move in the limiting hole and no longer be tightened in the limiting groove. The connecting rod can be taken out from the connecting tube. After releasing the sliding sleeve, the sliding sleeve is reset under the action of the reset spring, and the tightening ring tightens the limiting ball in the limiting hole again, so that the limiting ball cannot move in the limiting hole. This solution has a simple structure, can effectively tighten the limiting ball in the limiting groove, thereby effectively realizing the limitation of the connecting rod and the connecting tube, and is easy to operate, and can be realized by only sliding the sliding sleeve.

[0024] Preferably, as an improvement, a limiting ring is provided on the top of the sliding sleeve, a clamping ring is provided on the outer wall of the connecting tube, and the limiting ring abuts against the clamping ring.

[0025] Beneficial effect: In this scheme, a limiting ring and a clamping ring that abut against each other are arranged on the top of the sliding sleeve and the outer wall of the connecting tube. When the sliding sleeve is loosened after the disassembly of the baffle body is completed, and the limiting spring drives the sliding sleeve to slide upward relative to the connecting seat and reset, the clamping ring can abut against the limiting ring to limit the position of the sliding sleeve, so that the sliding sleeve can be quickly reset; at the same time, the setting of the clamping ring and the limiting ring allows the reset spring to be directly mounted on the connecting tube without the need to fix the top and bottom of the reset spring to the clamping ring and the connecting seat respectively, which is convenient for installation and disassembly and replacement.

[0026] Preferably, as an improvement, the diameter of the limiting hole gradually increases radially outwardly of the connecting tube, and the minimum diameter of the limiting hole is smaller than the diameter of the limiting ball.

[0027] Beneficial effect: In this scheme, the diameter of the limiting hole is set to gradually increase radially outward along the connecting tube, which is convenient for installing the limiting ball from the outer wall of the connecting tube; at the same time, the minimum diameter of the limiting hole is set to be smaller than the diameter of the limiting ball, which can ensure that the limiting ball can be pressed against the limiting groove under the extrusion of the tightening ring, and avoid the limiting ball rolling from the limiting hole into the limiting tube when / after the connecting rod is pulled out of the connecting tube. Therefore, this scheme can conveniently install a new baffle body after disassembling the scratched baffle body.

[0028] Preferably, as an improvement, the groove wall of the limiting groove is arc-shaped, and the limiting ball fits with the groove wall of the limiting groove.

[0029] Beneficial effect: In this scheme, the groove wall of the limit groove is set to an arc shape that fits with the limit ball. When the limit ball is pressed in the limit groove by the tightening ring, the groove wall of the limit groove fits with the limit ball, which can effectively improve the position stability of the limit ball in the limit groove, thereby improving the position limit stability of the connecting rod by the limit member, which is beneficial to ensure the position stability of the baffle body during use, and further achieve effective shielding of flying bone chips and blood, ensuring the safety of medical staff and patients during surgery.

[0033] Figure 4 This is a schematic diagram of the connection structure between the connecting part and the connecting seat in Example 3 of the utility model. DETAILED DESCRIPTION

[0034] The following is further described in detail through specific implementation methods:

[0035] The figure marks in the drawings of the specification include: baffle body 1, shielding part 11, connecting part 12, handle 2, connecting seat 3, ball hinge 4, ball shell 41, ball head 42, ball hinge rod 43, connecting part 5, connecting rod 51, connecting tube 52, limiting part 6, limiting groove 61, limiting hole 62, limiting ball 63, fastening part 7, sliding sleeve 71, fastening ring 72, return spring 73, limiting ring 8, and retaining ring 9.

[0036] Example 1

[0037] A splash shield for orthopedic surgery, as shown in the attached Figure 1 and Figure 2As shown, it includes a transparent baffle body 1 and a handle 2 fixedly connected (specifically, it can be bonded) to the bottom of the baffle body 1. The baffle body 1 is an arc-shaped baffle body 1, and the baffle body 1 is tilted inward relative to the handle 2. It should be noted that "tilted inward" refers to tilting toward the inner arc side of the arc-shaped baffle body 1, and also tilting toward the side of the baffle body 1 close to the surgical site when the baffle body 1 is in use. The baffle body 1 includes an integrally formed shielding portion 11 and a connecting portion 12, and the connecting portion 12 is located between the shielding portion 11 and the handle 2, and the width of the connecting portion 12 gradually decreases from top to bottom.

[0038] In this embodiment, the overall height of the splash shield is 30 cm, of which the height of the handle 2 is 10 cm, the height of the shielding portion 11 of the shield body 1 is 13 cm, and the height of the connecting portion 12 of the shield body 1 is 7 cm; the arc length of the shield body 1 is 20 cm, and the straight-line distance between the two sides of the shield body 1 is 15 cm; the thickness of the shield body 1 is 2 mm, and the inclination angle of the shield body 1 relative to the handle 2 is 10°. The shield body 1 is a high-definition transparent acrylic shield body 1, which can ensure a clear surgical field of view. The surface of the handle 2 is frosted to increase the friction of the handle 2 surface, thereby playing an anti-slip role during use.

[0039] The specific implementation process is as follows:

[0040] When an electric saw is used to cut bones and joint bones at the surgical site during orthopedic surgery, the medical staff holds the splash shield by the handle 2 and moves the shield body 1 above the surgical site to shield the surgical site, thereby preventing bone chips and blood generated during the cutting process from splashing around. This not only ensures the safety and hygiene of the medical staff and reduces or even avoids the risk of occupational exposure of the medical staff, but also prevents the splashed bone chips from contacting the non-sterile area. Even if the bone chips are bounced back to the sterile area after contacting the shield body 1, the risk of surgical infection can be reduced or even avoided.

[0041] After the operation is completed, the splash shield is returned to the hospital's disinfection supply center along with other surgical instruments for cleaning, disinfection and sterilization, and then sealed and packaged for storage until it is opened and used before the operation to ensure that the splash shield meets sterility requirements.

[0042] Example 2

[0043] A splash shield for orthopedic surgery, as shown in the attached Figure 3As shown, the difference from Example 1 is that the shielding portion 11 is hinged to the handle 2 to adjust the tilt angle of the baffle body 1 relative to the handle 2. Specifically, the bottom of the shielding portion 11 is fixedly connected (specifically, it can be bonded) with a connecting seat 3, and the connecting seat 3 and the handle 2 are connected via a ball hinge 4. The ball hinge 4 adopts the ball hinge 4 of the prior art, including a ball shell 41, a ball head 42 and a ball hinge rod 43, the ball shell 41 is fixedly connected to the middle position of the top of the handle 2, the ball hinge rod 43 is coaxially fixedly connected to the bottom of the connecting seat 3, the ball head 42 is welded and fixed to the bottom of the ball hinge rod 43, and the ball center of the ball head 42 is located on the axis of the ball hinge rod 43, and the ball hinge is rotatably connected in the ball shell 41.

[0044] It should be noted that the rotational friction between the ball head 42 and the ball shell 41 is very large, and the user needs to continuously apply force to allow the ball head 42 to rotate relative to the ball shell 41. The ball head 42 will not rotate spontaneously relative to the ball shell 41.

[0045] Compared with Example 1, this embodiment can adjust the inclination angle of the baffle body 1 relative to the handle 2, so that the splash shield can be applied to more orthopedic surgery operation scenarios, thereby improving the practicality of the splash shield.

[0046] Example 3

[0047] A splash shield for orthopedic surgery, as shown in the attached Figure 4 As shown, the difference between it and the second embodiment is that a connecting member 5 is provided between the shielding portion 11 and the connecting seat 3, and the connecting member 5 is used to realize the detachable connection between the baffle body 1 and the handle 2. Specifically, the connecting member 5 includes a connecting rod 51 and a connecting cylinder 52, the connecting rod 51 is fixedly connected to the bottom middle position of the connecting portion 12 of the baffle body 1, and the connecting cylinder 52 is coaxially fixedly connected to the top of the connecting seat 3, and the outer diameter of the connecting cylinder 52 is smaller than the diameter of the connecting seat 3; the connecting rod 51 is axially slidably connected in the connecting cylinder 52, and a limiter 6 for limiting the position of the connecting rod 51 is provided between the connecting rod 51 and the connecting cylinder 52.

[0048] The limiting member 6 includes a limiting groove 61, a limiting hole 62 and a limiting ball 63. The limiting groove 61 is opened on the side wall of the connecting rod 51 along the circumferential direction of the connecting rod 51, and the limiting hole 62 is opened on the connecting tube 52 along the radial direction of the connecting tube 52. When the bottoms of the connecting rod 51 and the connecting tube 52 are flush (that is, when the connecting rod 51 is inserted into the bottom of the connecting tube 52), the limiting hole 62 is opposite to the limiting groove 61. The limiting ball 63 is movably placed in the limiting hole 62, and the diameter of the limiting ball 63 is greater than the thickness of the limiting tube. The limiting tube is provided with a tightening member 7 for tightening the limiting ball 63 in the limiting groove 61. The diameter of the limiting hole 62 gradually increases outward along the radial direction of the connecting tube 52, and the minimum diameter of the limiting hole 62 is smaller than the diameter of the limiting ball 63, so as to prevent the limiting ball 63 from falling from the limiting hole 62 into the connecting tube 52. The groove wall of the limiting groove 61 is arc-shaped, and when the limiting ball 63 is pressed against the limiting groove 61 by the pressing member 7 , the limiting ball 63 fits against the groove wall of the limiting groove 61 .

[0049] The abutting member 7 comprises a sleeve 71, a abutting ring 72 and a return spring 73. The sleeve 71 is axially slidably sleeved on the connecting seat 3. The abutting ring 72 is coaxially fixedly connected (specifically, it can be bonded) on the inner wall of the sleeve 71. The position of the abutting ring 72 is opposite to the position of the limiting hole 62. The abutting ring 72 is axially slidably sleeved on the connecting tube 52. The return spring 73 is sleeved on the connecting tube 52. The return spring 73 is located between the abutting ring 72 and the connecting seat 3. The top of the return spring 73 abuts against the bottom of the abutting ring 72. The bottom of the return spring 73 abuts against the top of the connecting seat 3. The top of the sleeve 71 is coaxially fixedly connected (specifically, it can be bonded) with a limit ring 8. The limit ring 8 is axially slidably sleeved on the connecting tube 52. A clamping ring 9 is coaxially sleeved on the outer wall of the connecting tube 52. The clamping ring 9 is tension-fixed on the connecting tube 52. The top of the limit ring 8 abuts against the bottom of the clamping ring 9.

[0050] In this embodiment, the thickness of the clamping ring 72 is greater than or equal to the thickness of the limiting groove 61, and the thickness of the clamping ring 72 is less than the diameter of the limiting ball 63. In this way, it can ensure that the connecting rod 51 can be smoothly taken out and inserted into the connecting tube 52, and prevent the limiting ball 63 from falling from the limiting hole 62 into the sliding sleeve 71, thereby ensuring subsequent normal use.

[0051] When in use, the tightening ring 72 presses the limiting ball 63 against the limiting groove 61, so that the limiting ball 63 cannot move in the limiting hole 62, and the relative position of the connecting rod 51 and the connecting tube 52 is fixed. When the baffle body 1 needs to be disassembled or connected, the sliding sleeve 71 is slid downward relative to the connecting seat 3, so that the tightening ring 72 is no longer in contact with the limiting ball 63. At this time, the reset spring 73 is compressed, and the limiting ball 63 can move in the limiting hole 62, so that the connecting rod 51 can be smoothly taken out or inserted into the connecting tube 52. Then the sliding sleeve 71 is released, and under the elastic force of the reset spring 73, the sliding sleeve 71 slides upward until the limiting ring 8 and the clamping ring 9 abut against the sliding sleeve 71 to limit the sliding sleeve 71. At this time, the sliding sleeve 71 is reset, and the tightening ring 72 presses the limiting ball 63 again, so that the limiting ball 63 cannot move in the limiting hole 62.

[0052] Compared with Example 2, this embodiment further realizes a detachable connection of the baffle body 1 relative to the handle 2 based on the adjustable inclination angle of the baffle body 1 relative to the handle 2. In this way, when the baffle body 1 is scratched by flying bone chips during use, the baffle body 1 can be replaced separately.

[0053] In other embodiments, the portion of the connecting rod 51 above the limiting groove 61 is cylindrical, and the portion of the connecting rod 51 below the limiting groove 61 is cube-shaped, and the cross section of the cylindrical shape is the inscribed circle of the cross section of the cube; the inner wall of the connecting cylinder 52 fits with the connecting rod 51. By setting the cube-shaped limiting rod portion below the limiting groove 61 and the connecting cylinder 52 fitting with the connecting rod 51, the circumferential rotation of the connecting rod 51 relative to the connecting cylinder 52 can be limited, thereby preventing the baffle body 1 from rotating during use, and ensuring the stability of the baffle body 1 during use.

[0054] The above is only an embodiment of the utility model, 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 utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
