Description

Technical Field

[0001] The present invention relates to the technical field of small surgical instruments, in particular to a special scissors for otolaryngology. Background Art

[0002] ENT surgical instruments are tools used in ENT surgery. ENT surgical instruments include ENT knives, chisels, scissors, tweezers, clamps, hooks and needles, etc., which are mainly used in ENT surgery.

[0003] Among them, scissors are often used in otolaryngology to remove polyps or tumors in the ear canal, nostril or throat cavity. This mainly relies on the doctor holding the surgical scissors and the patient's cooperation. In addition, there are the influence of various equipment or factors such as the visitor light (or endoscope), which makes the surgical scissors unable to be fixed, resulting in a high risk of the surgical scissors blade scratching the inner wall of the organ during the operation.

[0004] Therefore, the present invention attempts to reduce the risk of ENT surgery on the premise of increasing the fixation of surgical scissors. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a special scissors for otolaryngology.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A pair of special scissors for otolaryngology comprises a scissor body, which is formed by a scissor handle I and a scissor handle II hingedly connected via a support column, i.e., the middle portion and the head portion of the scissor handle I and the middle portion and the head portion of the scissor handle II are placed one above the other, and the heads of the scissor handle I and the scissor handle II are both provided with flat blade areas, the two sets of flat blade areas being close to each other to form a shearing structure, which can refer to the blades of existing scissors;

[0008] One end of the shearing handle I is provided with an annular hand-holding part I, and one end of the shearing handle II is provided with an annular hand-holding part II, and the annular hand-holding part I and the annular hand-holding part II are located in the same plane, that is, the shearing handle I and the shearing handle II have a twisted shape from the middle to the tail;

[0009] The support column runs through the middle of the shear handle I and the middle of the shear handle II to form a cross hinge structure. The ring-shaped hand-held part I and the ring-shaped hand-held part II are controlled by pinching the fingers to form a scissors structure, referring to the existing scissors structure;

[0010] The two ends of the support column are movably connected to the inner side of the support ring. Specifically, an annular groove is provided on the inner arc surface of the support ring, and arc-shaped sliders are provided at both ends of the support column. The width of the annular groove opening is larger than the diameter of the support column and smaller than the width of the arc-shaped slider, so that the support column can rotate freely along the arc length direction of the annular groove;

[0011] A fixing mechanism is connected to the side of the support ring away from the flat blade area. When in use, the support ring is placed at the mouth of the hole-shaped organ [including the ear hole, mouth or nostril], and the outer side of the support ring is against the mouth of the hole-shaped organ to support the opening to facilitate surgery. The fixing mechanism is arranged outside the hole-shaped organ and is used to reinforce the support ring to fix it, thereby facilitating the rotation of the support column to adjust the shearing direction of the flat blade area.

[0012] Preferably, in order to switch the support column between a rotatable state and a fixed state, a damping airbag I is provided on the inner wall of the annular groove, a rack I is distributed annularly on the surface of the damping airbag I, and a rack II is provided on the side of the arc-shaped slider away from the support column to cooperate with the rack I;

[0013] When the air pressure in the damping airbag I is lower than 0.05MPa, the rack I and rack II are separated, and the support column can rotate freely;

[0014] When the damping airbag I is filled with gas and the internal air pressure is maintained at 0.2 to 0.3 MPa, the rack I and the rack II engage with each other to limit the rotation of the support column.

[0015] Furthermore, rack I and rack II are both made of thin strips of hard rubber, forming an anti-slip belt to dampen and limit the rotation of the support column.

[0016] Furthermore, the damping airbag I is connected to a micro air pump I, such as a nano-scale air pump with a size less than 10-50 mm. The micro air pump I is arranged on the surface of the support ring away from the flat edge area.

[0017] Preferably, in order to achieve better fixation effect of the support ring and better fit to the skin, the outer arc of the support ring is connected with a damping airbag II, and the outer arc surface of the damping airbag II is paved with anti-slip bumps to prevent slipping and improve the patient's touch.

[0018] When the air pressure in the damping airbag II is lower than 0.05 MPa, the support ring can be pulled out of the porous organ;

[0019] When the damping airbag II is filled with gas and the internal air pressure is higher than 0.2 MPa, the damping airbag II can press against the inner wall of the porous organ to prevent the support ring from moving, thereby playing an auxiliary reinforcement role.

[0020] Furthermore, the anti-slip bumps are made of soft silicone material and have a frosted surface to prevent slipping.

[0021] Furthermore, the damping airbag II is connected to a micro air pump II, such as a nano-scale air pump with a size less than 10-50 mm. The micro air pump II is arranged on the surface of the support ring away from the flat edge area.

[0022] Preferably, in order to adjust the shearing position, positioning rings are respectively provided on the side away from each other in the middle of the shear handle I and the middle of the shear handle II, and the outer wall of the support column is provided with a thread. The positioning rings are sleeved on the outer wall of the support column through threaded fitting, which is used to prevent the shear handle I and the shear handle II from falling off and to adjust the distance between the two.

[0023] Furthermore, the outer wall of the positioning ring is in the shape of a hexagonal column, and the position of the positioning ring is adjusted by rotating it with a micro wrench.

[0024] Preferably, the fixing mechanism can be connected by a hollow headgear welded with a connecting rod and a steel bar. During the operation, the hollow headgear is put on the patient's head and fixed by a fixed support frame. It is especially suitable for children or patients allergic to anesthesia to limit their shaking during the operation and cause surgical accidents. The fixing mechanism can also be directly a fixed support frame to fix the position of the support ring.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention forms a novel scissors structure by having a support column extending through the middle of handles I and II. A positioning ring allows the scissors to be adjusted along the length of the support column. The support column rotates in a circular motion through the sliding engagement of the arc-shaped slider and the annular groove, thereby achieving translational and rotational position adjustment of the scissors and enabling precise alignment of the surgical site.

[0027] 2. The present invention cooperates with the rack I of the damping airbag I and the arc-shaped slider rack II to enable the support column to be positioned; the damping airbag II is connected to the outer arc surface, so that the support ring can fit tightly against the inner wall of the hole-shaped organ, and the support ring is fixedly installed through a fixing mechanism to ensure that the scissors cannot move during surgery, completely solving the surgical risks caused by shaking of existing surgical scissors, greatly improving surgical safety, and should be widely promoted for use.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] Example 1:

[0041] A pair of special scissors for otolaryngology includes a scissor body, which is formed by a scissor handle I 101 and a scissor handle II 102 hingedly connected via a support column 2. That is, the middle and head of the scissor handle I 101 and the middle and head of the scissor handle II 102 are placed one above the other, and the head of the scissor handle I 101 and the head of the scissor handle II 102 are both provided with a flat blade area 103. The two sets of flat blade areas 103 are close to each other to form a shearing structure, which can refer to the existing scissor blades;

[0042] One end of the shearing handle I 101 is provided with an annular hand-holding portion I 104, and one end of the shearing handle II 102 is provided with an annular hand-holding portion II 105, and the annular hand-holding portion I 104 and the annular hand-holding portion II 105 are located in the same plane, that is, the shearing handle I 101 and the shearing handle II 102 have a twisted shape from the middle to the tail;

[0043] The support column 2 passes through the middle of the shear handle I 101 and the middle of the shear handle II 102 to form a cross hinge structure. The ring-shaped hand-held part I 104 and the ring-shaped hand-held part II 105 are controlled by pinching the fingers to form a scissors structure, referring to the existing scissors structure;

[0044] The two ends of the support column 2 are movably connected to the inner side of the support ring 3. Specifically, an annular groove 301 is provided on the inner arc surface of the support ring 3, and arc-shaped sliders 201 are provided at both ends of the support column 2. The width of the opening of the annular groove 301 is larger than the diameter of the support column 2 and smaller than the width of the arc-shaped slider 201, so that the support column 2 can rotate freely along the arc length direction of the annular groove 301;

[0045] A fixing mechanism 4 is connected to the side of the support ring 3 away from the flat edge area 103. When in use, the support ring 3 is set at the mouth of the hole-shaped organ [including the ear hole, mouth or nostril], and the outer side of the support ring 3 is against the mouth of the hole-shaped organ to support the opening to facilitate surgery, while the fixing mechanism 4 is set outside the hole-shaped organ and is used to reinforce the support ring 3 to fix it, thereby facilitating the rotation of the support column 2 to adjust the shear direction of the flat edge area 103.

[0046] The fixing mechanism 4 can be a hollow headgear welded with steel bars, which is put on the patient's head during surgery and fixed by a fixed support frame. It is especially suitable for children or patients allergic to anesthesia to limit their shaking during surgery and cause surgical accidents. The fixing mechanism 4 can also be directly a fixed support frame to fix the position of the support ring 3.

[0047] Example 2:

[0048] On the basis of Example 1, in order to switch the support column 2 between a rotatable state and a fixed state, a damping airbag I 5 is provided on the inner wall of the annular groove 301. A rack I 501 is distributed annularly on the surface of the damping airbag I 5. A rack II 202 cooperating with the rack I 501 is provided on the side of the arc-shaped slider 201 away from the support column 2.

[0049] When the air pressure in the damping airbag I5 is lower than 0.05 MPa, the rack I501 is separated from the rack II202, and the support column 2 can rotate freely;

[0050] When the damping airbag I5 is filled with gas and the internal pressure is maintained at 0.2 to 0.3 MPa, the rack I501 and the rack II202 engage with each other to limit the rotation of the support column 2.

[0051] Furthermore, rack I 501 and rack II 202 are both made of thin strips of hard rubber, forming an anti-slip belt to dampen and limit the rotation of the support column 2.

[0052] Furthermore, the damping airbag I5 is connected to a micro air pump I502, such as a nano-scale air pump with a size less than 10-50 mm. The micro air pump I502 is arranged on the surface of the support ring 3 away from the flat edge area 103.

[0053] Example 3:

[0054] On the basis of Example 2, in order to achieve better fixation of the support ring 3 and better fit to the skin 2, the outer arc surface of the support ring 3 is connected with a damping airbag II 6, and the outer arc surface of the damping airbag II 6 is paved with anti-slip bumps 601, which play the role of anti-slip and improving the patient's touch.

[0055] When the air pressure in the damping airbag II 6 is lower than 0.05 MPa, the support ring 3 can be pulled out of the porous organ;

[0056] When the damping airbag II 6 is filled with gas and the internal pressure is higher than 0.2 MPa, the damping airbag II 6 can press against the inner wall of the porous organ to prevent the support ring 3 from moving, thereby playing an auxiliary reinforcement role.

[0057] Furthermore, the anti-slip bumps 601 are made of soft silicone material and have a frosted surface to prevent slipping.

[0058] Furthermore, the damping airbag II 6 is connected to a micro air pump II 602 , such as a nano-scale air pump with a size less than 10-50 mm. The micro air pump II 602 is arranged on the surface of the support ring 3 away from the flat edge area 103 .

[0059] Example 4:

[0060] On the basis of Example 3, in order to adjust the shearing position, positioning rings 203 are respectively provided on the side away from each other in the middle of the shearing handle I 101 and the middle of the shearing handle II 102, and the outer wall of the support column 2 is provided with a thread. The positioning ring 203 is sleeved on the outer wall of the support column 2 through threaded fitting, which is used to prevent the shearing handle I 101 and the shearing handle II 102 from falling off and to adjust the distance between the two.

[0061] The outer wall of the positioning ring 203 is in the shape of a hexagonal column, and the position of the positioning ring 203 is adjusted by rotating it with a micro wrench.

[0062] The working process of the preferred embodiment 4 is as follows: Figure 3-10 As shown:

[0063] 1) If Figure 4 As shown, the support ring 3 is placed in the hole-shaped organ, the damping airbag II 6 is pressurized to basically fix the support ring 3, the positions of the two positioning rings 203 are adjusted so that the flat edge area 103 reaches the fitting distance of the predetermined patient part, and then the fixing mechanism 4 is installed to completely fix the support ring 3;

[0064] 2) If Figure 6 and Figure 8 As shown, the support column 2 is rotated so that the flat edge area 103 reaches the accurate patient site. During this period, the positions of the two positioning rings 203 can be adjusted again, and the pressurized damping airbag Ⅰ5 makes the support column 2 unable to rotate, as shown in FIG. Figure 10 As shown, surgery was performed;

[0065] 3) After the operation is completed, forceps can be used to clamp the cut patient body, decompress the damping airbag II 6, uninstall the fixing mechanism 4, and remove the support ring 3 to complete the operation.

[0066] Example 5:

[0067] On the basis of Example 4, a connecting line 701 is fixed to the outer wall of the support column 2 through a strip 204. An endoscope 702 is provided at one end of the connecting line 701. The endoscope 702 is fixedly mounted on the handle Ⅰ 101 near the flat blade area 103 and is used for surgical observation of the cutting position for adjustment.

[0068] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
