Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

Example (b):

referring to fig. 1-5, a cartilage slicer for plastic surgery comprises a bottom plate 1, wherein a stop block 2 and a fixed block 3 which are parallel to each other are oppositely arranged on the upper surface of the bottom plate 1, a slide bar 4 is arranged between the stop block 2 and the fixed block 3, and the slide bar 4 is respectively vertical to the stop block 2 and the fixed block 3; a slide block 5 is arranged on the slide rod 4 in a penetrating way, two blades 6 with the blade parts capable of being attached to the upper surface of the bottom plate 1 are arranged on the slide block 5, and the two blades 6 are both parallel to the stop block 2; the ends of the two blades 6 far away from the sliding block 5 are both arranged on a connecting block 7, and a rotating handle 8 is arranged on the connecting block 7; be provided with the screw hole on the fixed block 3, wear to be equipped with in the screw hole of fixed block 3 with screw hole assorted adjusting screw 9, the end that adjusting screw 9 is located between dog 2 and the fixed block 3 articulates through the bulb has briquetting 10, the end that adjusting screw 9 is located outside bottom plate 1 is provided with adjust knob 11.

In the embodiment, the cartilage can be taken from the soft rib of the human body, when the cartilage is taken down for slicing, the cartilage is placed between the pressing block 10 and the stop block 2 on the bottom plate 1, then the first adjusting knob 11 is rotated to enable the pressing block 10 to move towards the stop block 2 until the cartilage is clamped between the stop block 2 and the pressing block 10, and the soft rib is prevented from slipping and falling or fingers are damaged due to improper cutting; the threaded holes in the fixing block 3 and the fixing block 3 provide supporting counter force for the adjusting screw 9, so that clamping of cartilage is achieved. Then handheld rotatory handle 8 is pressed blade 6 to bottom plate 1 direction, makes the cutting part of blade 6 surely get cartilage, surely gets the in-process owing to adopt two blades 6 that are parallel to each other, once surely gets just can obtain the section that a thickness is even and both sides are smooth no burr, need not to carry out secondary cutting, convenient operation.

Connecting pieces 12 are respectively arranged at two ends of the two blades 6, grooves are respectively formed in the sliding block 5 and the connecting block 7, the grooves of the sliding block 5 and the connecting block 7 are oppositely arranged, and bidirectional screws 13 vertical to the blades 6 are respectively arranged in the grooves of the sliding block 5 and the connecting block 7; one ends of the two bidirectional screw rods 13 are hinged to the side walls of the grooves, the other ends of the two bidirectional screw rods 13 extend out of the grooves, and adjusting knobs II 14 are arranged at the ends of the two bidirectional screw rods 13 extending out of the end parts of the grooves; threaded holes matched with the two-way screws 13 are formed in the connecting piece 12, and the two blades 6 are fixed between the two-way screws 13 in parallel through the connecting piece 12. The two-way screw 13 is formed by coaxially connecting two screws with opposite thread directions (as shown in fig. 5), and the two connecting pieces 12 sleeved on the same two-way screw 13 can move oppositely or oppositely along with the rotation of the two-way screw 13; before the cartilage section is cut, the distance between the two blades 6 can be adjusted by respectively rotating the two adjusting knobs 14, and the requirements of cartilage sections with different thicknesses are met.

One surface of the connecting piece 12, which is far away from the bidirectional screw 13, is provided with a slot 18 for inserting the blade 6, and the outer wall of the connecting piece 12 is also provided with a tightening bolt 19 for fixing the end of the blade 6 in the slot 18. The blade 6 is generally cut at one time, when slicing is needed, one end of the blade 6 is inserted into the slot 18 of one connecting piece 12, the other end of the blade 6 is inserted into the slot 18 of the other corresponding connecting piece 12, then the two ends of the blade 6 are screwed and fixed in the slots 18 of the two connecting pieces 12 by the screwing bolts 19, and soft rib slicing can be carried out after the two blades 6 are fixed. After slicing is completed, the bolt 19 is loosened and tightened, and the blade 6 is detached, so that the blade 6 can be replaced by a new blade 6 for next slicing.

Referring to fig. 1-4, dials are circumferentially arranged on the connecting block 7 and the sliding block 5 at the edges close to the second adjusting knobs 14, and pointers pointing to the corresponding dials are arranged at the edges of each second adjusting knob 14. The arrangement of the dial scale can visually represent the distance between the two blades 6, the initial position of the pointer points to zero, the distance between the two blades 6 is zero at the moment, and when the pointer points to scale values on the rest dial scale, the numerical values on the dial scale correspond to the distances between the blades 6; medical staff directly rotates the pointers of the two second adjusting knobs 14 to the corresponding dial scales according to the required cartilage slice thickness, so that the distance between the blades 6 can be quickly adjusted and positioned, and the operation is simple and convenient.

Referring to fig. 1 and 6, the adjusting screw 9 is sleeved with a sleeve 15 at the end close to the pressing block 10, a supporting rod 16 is fixed on the sleeve 15, and the end of the supporting rod 16 far away from the sleeve 15 is fixed on the pressing block 10. The adjusting screw 9 and the pressing block 10 are hinged in a spherical mode, so that the pressing block 10 cannot rotate along with the adjusting screw 9 when the adjusting screw 9 is rotated to push the pressing block 10; but when carrying out the centre gripping to cartilage, briquetting 10 deflects easily, leads to the centre gripping powerless, and cartilage slides easily, fixes sleeve 15 and briquetting 10 through bracing piece 16, and to cartilage centre gripping in-process, sleeve 15 and bracing piece 16 combined action can guarantee that briquetting 10 can not take place to deflect relative adjusting screw 9, and briquetting 10 and dog 2 can be better carry out the centre gripping to cartilage, and the difficult production of cartilage slides in the centre gripping, and the blade 6 of being convenient for is surely got cartilage.

The bottom plate 1 is generally made of a metal material, and the blade portion of the blade 6 contacts the bottom plate 1 after cutting off cartilage, so that the blade is damaged, and the next cutting is difficult. In this embodiment, a plurality of fine and dense knife edge grooves 17 are designed on the bottom plate 1 to match the positions of the knife edges when the knife edges fall down, so that the knife edges do not contact the metal bottom plate 1 after cutting.

The embodiment of the present invention is the above. The specific parameters in the above embodiments and examples are only for the purpose of clearly showing the verification process of the present invention, and are not used to limit the protection scope of the present invention, which is still subject to the claims, and all the equivalent structural changes made by using the contents of the specification and drawings of the present invention should be included in the protection scope of the present invention.
