Description

Blade with anti-slip function and brain traction device using the same

[0001] The present invention relates to a blade equipped with an anti-slip means on a blade provided with a brain traction device, which prevents slippage after the brain has been opened with the blade to secure a surgical field of view.

[0002] Unlike early neurosurgical procedures that treated only initial head trauma, the scope of treatment has recently expanded to include the treatment of cerebrovascular diseases, brain tumors, and deep brain lesions.

[0003] As a result, brain traction has become an indispensable element to improve visibility and surgical safety during brain surgery, and consequently, much research is being conducted on brain traction devices.

[0004] As shown in Fig. 1, the brain traction device currently in general use is fixed to a surgical table or to the scalp and skull. This not only consumes a lot of time during the surgical preparation process, but also, because the fixation device used for traction is large and located far from the surgical site, the length of the traction arm used to fix the blade used for actual brain traction to the surgical site is designed to be considerably long.

[0005] Meanwhile, as shown in FIG. 2, the blades used in conventional brain traction devices are provided in pairs with smooth surfaces made of tungsten or stainless steel to open the brain portion to be operated on both sides, thereby allowing the operator to secure a clear view. However, there is a problem in that safety accidents occur when the blades slip and detach after or during the process of opening the brain.

[0006] In addition, conventional brain traction devices have another problem in that, after installation, the surgeon's field of view and movement required during surgery are restricted, and there is a very high risk of safety accidents, such as the blade penetrating the brain due to even a slight impact caused by the surgeon's inattention, or damage to the normal brain caused by the excessive spreading of a pair of blades.

[0007] The purpose is to prevent safety accidents by preventing slippage of the part in contact with the brain when using the blade mounted on the brain traction device of the present invention, in order to solve the aforementioned conventional problems.

[0008] In addition, the purpose of the present invention is to solve another problem of the prior art by miniaturizing the traction device, making it easy to change the position according to the operator's position, thereby reducing the length of the blade traction arm, and improving visibility to prevent safety accidents.

[0009] As a means of solving the problem of the aforementioned conventional problems, the blade having an anti-slip function according to the present invention includes an anti-slip means for preventing slippage on the surface that contacts the brain, wherein the anti-slip means is characterized by including a silicone cover (211) that is replaceably inserted into the outer surface of the blade, and a pattern portion (215) formed on the outer surface of the silicone cover (211) that contacts the brain to prevent slippage of the blade.

[0010] Meanwhile, as a means of solving another problem of the conventional method described above, a first embodiment of a brain traction device using a blade having an anti-slip function according to the present invention comprises a body (100), a pair of traction arms (200) provided symmetrically to each other, each having one side rotatably coupled to the body (100) and each having a blade (210) for spreading the brain to a predetermined width on the other side, and an elastic body (300) disposed between the pair of traction arms (200) and applying an external force to spread the pair of traction arms (200) by means of elastic force, wherein a replaceable anti-slip means is provided on the outer surface of the blade (210), and the anti-slip means comprises a silicone cover (211) that is replaceably inserted into the outer surface of the blade (210), and a pattern part (215) formed on the outer surface of the silicone cover (211) that contacts the brain to prevent the blade (210) from slipping.

[0011] Additionally, it is preferable that the body (100) is provided with an angle control pin (130) for controlling the rotation angle of a pair of traction arms (200) that are spread apart by an elastic body (300).

[0012] In addition, it is preferable that the gap between the pair of traction arms (200) spread by the elastic body (300) is 1 cm to 1.5 cm.

[0013] Additionally, it is preferable that a pair of the above-mentioned traction arms (200) include a bent portion (220) formed by bending at a predetermined angle.

[0014] Meanwhile, as a means of solving the problem of another conventional problem described above, a second embodiment of a brain traction device using a blade having an anti-slip function according to the present invention comprises a body (100), a pair of traction arms (200) provided symmetrically with each other, each having one side rotatably coupled to the body (100) and each having a blade (210) for spreading the brain to a predetermined width on the other side, an expansion body (400) disposed between the pair of traction arms (200) and applying an external force so that the pair of traction arms (200) can spread apart or narrow depending on whether or not they are supplied by an expansion inducer, and an injection pipe (410) connected to the expansion body (400) to provide a passage for the expansion inducer to enter and exit, wherein the expansion inducer is saline solution, and a replaceable anti-slip means is provided on the outer surface of the blade (210), wherein the anti-slip means is a silicone that is replaceably inserted into the outer surface of the blade (210). It is characterized by including a cover (211) and a pattern portion (215) formed on the outer surface of the silicone cover (211) that contacts the brain to prevent slippage of the blade (210).

[0015] Additionally, the body (100) is preferably equipped with an angle control pin (130) that controls the rotation angle of a pair of traction arms (200) that are spread apart by the expansion body (400).

[0016] Additionally, the expansion body (400) is formed such that both sides are connected to a pair of traction arms (200), and the expansion width of one side is greater than the expansion width of the other side, and it is preferable that the expansion width of one side of the expansion body (400) be such that the distance between the pair of traction arms (200) is 1 cm to 1.5 cm.

[0017] According to the present invention, a slip prevention means is detachably provided on the outer surface of the blade, which is distinct from the prior art, thereby allowing for the effect of preventing slippage by the pattern portion of the silicone cover that comes into direct contact with the brain when the pair of blades are spread apart to secure a surgical field of view.

[0018] In addition, unlike conventional devices, this device satisfies the miniaturization of the brain traction device while allowing the body to be fixed at a position desired by the operator, thereby enabling free positional changes and a reduction in the length of the traction arm. Furthermore, it is expected to have the effect of preventing safety accidents by improving the operator's field of vision.

[0025] FIG. 8 is a drawing illustrating a blade having an anti-slip function according to the present invention.

[0026] Hereinafter, a blade having an anti-slip function according to the present invention and a brain traction device using the same will be described in detail with reference to the attached drawings.

[0027] Before the explanation, as illustrated in FIGS. 3 and FIGS. 5, the traction device according to the present invention can be implemented in a first embodiment (1) and a second embodiment (2). Note that the first embodiment (1) is a method in which a pair of traction arms (200) described later are spread apart by elastic force, whereas the second embodiment (2) is a method in which a pair of traction arms (200) can be spread apart by expansion force. To ensure this is clearly understood, each embodiment will be described below.

[0028] First, as illustrated in FIGS. 3 and 4, the traction device according to the first embodiment (1) of the present invention comprises a body (100), a traction arm (200), and an elastic body (300).

[0029] To explain in more detail, the body (100) is configured to provide an installation site where a pair of traction arms (200), which will be described later, can be installed on an elastic body (300) to spread apart or narrow, as described above, and at the same time to control the separation and spreading rotation angle of the traction arms (200).

[0030] As described above, the body (100) may include a lower body (110) that can be separated and assembled from each other and an upper body (120) formed in the shape of a cap, and a through hole (121) may be formed on the outer surface of the upper body (120) to allow a pair of traction arms (200) to be inserted through it so as to be exposed to the outside.

[0031] In addition, the separation assembly between the lower body (110) and the upper body (120) can be performed using a screw thread assembly method or a method of fitting together in a male and female form through protrusions and grooves.

[0032] As shown in the illustration, one side of each traction arm (200), which is composed of a pair, is rotatably axially coupled to the upper surface of the lower body (110), and the axially coupled pair of traction arms (200) satisfy a structure in which they are exposed to the outside through a through hole (121).

[0033] At this time, it is preferable that each traction arm (200), which is rotatably axially coupled to the upper surface of the lower body (110), is connected to have a structure that is separable from the lower body (110) so that maintenance of the traction arm (200) is possible.

[0034] In addition, a pair of angle control pins (130) are formed protruding from the upper surface of the lower body (110) to control the rotation angle of the traction arms (200) that spread out when the traction arms (200) are rotatably fixedly coupled to the lower body (110) and spread out by the elastic force of the elastic body (300) described later.

[0035] At this time, it is preferable that the distance between the pair of angle control pins (130) formed on the lower body (110) be formed such that the pair of traction arms (200) can be spread apart by the elastic force of the elastic body (300) to have a gap (D) of 1.0 cm to 1.5 cm.

[0036] Here, the numerical limit of the gap (D) for a pair of traction arms (200) means that it can be widened through a pair of traction arms (200) without causing damage to the brain.

[0037] Meanwhile, although not illustrated, the lower part of the body (100) may further include a fixing means (not illustrated) for fixing the traction device according to the present invention to a bed on which a patient is lying, and although not illustrated, the fixing means may use a conventional detachable fixing means such as a clamp shape or a clamp shape that is attached to and detached from the bed frame by tightening a bolt.

[0038] And, the above-described traction arm (200) includes a blade (210) configured to provide convenience for brain surgery through rotation, with a pair of blades installed symmetrically on the body (100) described above so as to be able to rotate by means of an elastic body (300) to be described later.

[0039] Each traction arm (200) may include a bent portion (220) formed at a predetermined angle so that, as described above, the operator can secure the desired gap (D) of the brain without excessive spreading of the elastic body (300), and during the process of spreading the brain, the pair of traction arms (200) can maintain parallelism with each other to secure the gap (D).

[0040] The blade (210) comes into direct contact with the brain, allowing the operator to secure the necessary field of view for brain surgery through the opening of the traction arm (200).

[0041] The blade (210) is made of tungsten or stainless steel and has undergone a heat treatment process to be harmless to the human body.

[0042] On the outer surface of the blade (210), a slip prevention means may be further provided to prevent the blade (210) from detaching from the smooth and brittle surface of the traction arm (200) during the process of opening or after opening, and the slip prevention means may be applied in the same way to the first embodiment (1) as well as to the second embodiment (2) to be described later (see FIG. 8).

[0043] As described above, the anti-slip means may include a silicone cover (211) and a pattern portion (215).

[0044] Here, the silicone cover (211) is detachably fitted onto the outer surface of the blade (210) corresponding to the area of ​​the blade (210).

[0045] The silicone cover (211) can be molded into the shape of a pocket with an insertion hole (213) formed for separation and connection with the blade (210), and it is particularly desirable that the side in contact with the brain can cover the entire surface of the blade (210).

[0046] At this time, a pattern portion (215) for preventing slippage with the brain is formed over the entire surface of one side of the silicone cover (211), and the pattern portion (215) can be formed in a manner such as intaglio or relief so as not to cause damage to the brain.

[0047] Also, it should be noted that the above elastic body (300) is configured to exert an external force to cause the pair of traction arms (200) described above to spread apart (D), and that in the present invention, a leaf spring may be applied, but is not limited thereto.

[0048] As described above, the elastic body (300) is fixedly installed so that both sides are in contact with the mutually facing surfaces of the pair of traction arms (200) so that the pair of traction arms (200) can always be kept apart by the elastic force (D).

[0049] Meanwhile, the traction device according to the second embodiment (2) of the present invention, as shown in FIGS. 5 to 7, comprises a body (100), a pair of traction arms (200) equipped with blades (210), and an expansion body (400). Since the body (100) and the pair of traction arms (200) have the same configuration and structure as the first embodiment (1) described above, a detailed description is omitted so as not to obscure the gist of the second embodiment (2).

[0050] For example, the expansion body (400) is rotatably coupled to the body (100) and is installed between a pair of traction arms (200) whose rotation angle is controlled by an angle control pin (130) to apply an external force to cause the traction arms (200) to spread apart or contract.

[0051] To this end, the expansion body (400) has a structure connected to one side of an injection pipe (410) through which an expansion inducer moves, as described above, and an injection means (420) for injecting the expansion inducer is provided on the other side of the injection pipe (410).

[0052] Here, the expansion inducer uses saline solution to enable the expansion body (400) to perform the function of a hydraulically controlled actuator, and the injection means (420) may use a syringe or a pump capable of supplying and discharging saline solution.

[0053] Of course, in addition to saline solution, the expansion inducer in the present invention may use air to control the degree of expansion of the expansion body (400) according to the degree of air injection, but it is preferable to use saline solution that can be easily found in hospitals.

[0054] A mold can be formed on the surface so that the expansion volume can be freely applied differently depending on the supply amount of the expansion inducer of the expansion body (400), and through this, unlike the first embodiment (1) described above, it is possible to adjust the gap (D) through which a pair of traction arms (200) can spread within the limit of the angle control pin (130).

[0055] At this time, it is preferable that the expansion body (400) in the present invention expands so that the expansion width (H1) on one side facing the blade (210) after expansion is larger than the expansion width (H2) on the other side, so that a pair of traction arms (200) can be arranged parallel to each other when they form a maximum gap (D) until interference occurs by the angle control pin (130), thereby improving visibility of the surgical site after brain dilation.

[0056] As described above, the traction device according to the first embodiment (1) or the second embodiment (2) of the present invention is expected to have the effect of preventing slippage by means of the pattern portion (215) of the silicone cover (211) that comes into direct contact with the brain when the pair of blades (210) are spread apart to secure a surgical field of view, through a slippage prevention means that is detachably provided on the outer surface of the blade (210) in a manner distinct from the conventional method.

[0057] In addition, unlike conventional devices, the body (100) can be fixed at a position desired by the operator while satisfying the miniaturization of the brain traction device, allowing the operator to freely change their position and thus enabling a reduction in the length of the traction arm (200). Furthermore, the operator's ability to see clearly is improved, which is expected to prevent safety accidents.
